发明的详细描述Detailed description of the invention
本发明提供结合CD38的肽(“CD38BPs”),它可用于治疗、诊断和预防各种由表达CD38的细胞参与的疾病,例如多发性骨髓瘤。The present invention provides CD38-binding peptides ("CD38BPs") that are useful in the treatment, diagnosis and prevention of various diseases involving CD38-expressing cells, such as multiple myeloma.

抗体主要通过位于6个重链和轻链互补决定区(CDRs)的氨基酸残基与靶抗原相互作用。因此,在各个抗体间,CDRs中的氨基酸序列比CDRs之外的序列变异更多。由于CDR序列负责大部分抗体-抗原相互作用,因此可通过将来自特定天然存在的抗体CDR序列移植到来自具有不同特性的不同抗体的同框序列中而构建的表达载体来表达可模拟特定天然存在的抗体的性质的重组抗体(参见例如Riechmann,L.etal.,Nature 332,323-327(1998)、Jones,P.et al.,Nature 321,522-525(1986)and Queen,C.et al.,PNAS USA 86,10029-10033(1989))。Antibodies interact with target antigens primarily through amino acid residues located in the six heavy and light chain complementarity determining regions (CDRs). Thus, the amino acid sequences within the CDRs vary more among individual antibodies than sequences outside the CDRs. Since CDR sequences are responsible for most antibody-antigen interactions, expression vectors that can mimic specific naturally occurring antibodies can be expressed by grafting CDR sequences from a specific naturally occurring antibody into in-frame sequences from a different antibody with different properties. The recombinant antibody of the property of the antibody (see for example Riechmann, L. et al., Nature 332, 323-327 (1998), Jones, P. et al., Nature 321, 522-525 (1986) and Queen, C.et al., PNAS USA 86, 10029-10033 (1989)).

术语免疫球蛋白是指一类结构相关的糖蛋白,由两对多肽链组成,一对为轻的(L)低分子量链,一对是重(H)链,所有四条链通过二硫键内部连接。免疫球蛋白的结构已被详细描述。参见,例如FundamentalImmunology,第七章(Paul,W.,ed.,2nd ed.Raven Press,N.Y.(1989))。简言之,每个重链典型地包括重链可变区(此处缩写为VH)和重链恒 定区。重链恒定区典型地包括三个结构域,CH1、CH2和CH3。每个轻链典型地包括轻链可变区(此处缩写为VL)和轻链恒定区。轻链恒定区典型地包括一个结构域CL。VH和VL区可进一步细分为高变区(或结构确定的环的序列和/或形式可高度变化的高变区),也称为互补决定区(CDRs),其中散布着更保守的称为框架区(FRs)的区域。The term immunoglobulin refers to a class of structurally related glycoproteins consisting of two pairs of polypeptide chains, one pair of light (L) low molecular weight chains and one pair of heavy (H) chains, all four chains are internally linked by disulfide bonds connect. The structure of immunoglobulins has been described in detail. See, eg, Fundamental Immunology, Chapter 7 (Paul, W., ed., 2nd ed. Raven Press, NY (1989)). Briefly, each heavy chain typically includes a heavy chain variable region (abbreviated herein as VH ) and a heavy chain constant region. The heavy chain constant region typically includes three domains, CH1 , CH2 and CH3 . Each light chain typically includes a light chain variable region (abbreviated herein as VL ) and a light chain constant region. The light chain constant region typically includes one domain, CL . The VH and VL regions can be further subdivided into hypervariable regions (or hypervariable regions in which the sequence and/or form of structurally defined loops can be highly variable), also called complementarity determining regions (CDRs), interspersed with more conserved regions called framework regions (FRs).
每个VH和VL典型地包括3个CDRs和4个FRs,从氨基末端到羧基末端以如下顺序排列:FR1、CDR1、FR2、CDR2、FR3、CDR3、FR4(也参见Chothia and Lesk J.MoI.Biol.196,901-917(1987))。典型地,该区氨基酸残基的数目通过Kabat et al.,Sequences of ProteinsofImmunological Interest,第五版,Public Health Service,National InstitutesofHealth,Bethesda,MD.(1991)中所述的方法测定(诸如按Kabat中或根据此处Kabat进行编号的可变结构域残基这样的短语,是指用于重链可变结构域或轻链可变结构域的编号系统)。使用该编号系统,肽的实际线性氨基酸序列可含有更少的或额外的氨基酸,相当于可变结构域的FR或CDR的缩短或插入。例如,重链可变结构域可包括在VH CDR2的残基52后有单个氨基酸的插入(根据Kabat的残基52a)和在重链FR残基82后有插入的残基(例如根据Kabat的残基82a、82b和82c等)。对给定的抗体,残基的Kabat编号可通过将抗体序列的同源区与“标准的”Kabat编号序列比对后而确定。Each VH and VL typically includes 3 CDRs and 4 FRs, arranged from amino-terminus to carboxy-terminus in the following order: FR1, CDR1, FR2, CDR2, FR3, CDR3, FR4 (see also Chothia and Lesk J. MoI. Biol. 196, 901-917 (1987)). Typically, the number of amino acid residues in this region is determined by the method described in Kabat et al., Sequences of Proteins of Immunological Interest, Fifth Edition, Public Health Service, National Institutes of Health, Bethesda, MD. (1991) (such as in Kabat Or phrases such as variable domain residues numbered according to Kabat here refer to the numbering system used for heavy chain variable domains or light chain variable domains). Using this numbering system, the actual linear amino acid sequence of a peptide may contain fewer or additional amino acids corresponding to shortenings or insertions of FRs or CDRs of the variable domains. For example, the heavy chain variable domain may include a single amino acid insertion after residue 52 of the VH CDR2 (residue 52a according to Kabat) and an insertion after residue 82 of the heavy chain FR (e.g., according to Kabat Residues 82a, 82b and 82c of , etc.). For a given antibody, the Kabat numbering of residues can be determined by aligning the homologous regions of the antibody sequence with "standard" Kabat numbering sequences.

免疫球蛋白分子的重链和轻链可变区含有与抗原相互作用的结合结构域。抗体(Abs)的恒定区可介导免疫球蛋白与宿主组织或因子,包括免疫系统的各种细胞(例如效应细胞)和典型的补体系统的第一成分(Clq)的结合。The variable regions of the heavy and light chains of immunoglobulin molecules contain binding domains that interact with antigens. The constant regions of antibodies (Abs) mediate the binding of the immunoglobulin to host tissues or factors, including various cells of the immune system (eg, effector cells) and typically the first component (Clq) of the complement system.
抗CD38抗体可以为双特异性抗体、双功能抗体或相似分子(参见,例如PNAS USA90(14),6444-8(1993)描述的双功能抗体)。实际 上,本发明提供的双特异性抗体,双功能抗体等可与除CD38部分外的任何其它合适的靶结合。Anti-CD38 antibodies may be bispecific antibodies, bifunctional antibodies or similar molecules (see, eg, bifunctional antibodies described in PNAS USA 90(14), 6444-8 (1993)). In fact, the bispecific antibodies, diabodies, etc. provided by the present invention can bind to any other suitable target except the CD38 portion.
如上所述,除非文中特别说明或明确矛盾,此处术语抗体包括具有特异结合抗原能力的抗体部分。已表明抗体的抗原结合功能可通过全长抗体的片段来完成。结合片段的例子包括在术语“抗体”中,包括(i)Fab片段,含有VL、VH、CL和CH1结构域的单价片段;(ii)F(ab)2 和F(ab′)2片段,含2个Fab在铰链区通过二硫键连接的片段的双价片段;(iii)主要由VH和CH1结构域组成的Fd片段;(iv)主要由抗体的单个臂的VL和VH结构域组成的Fv片段;(v)dAb片段(Ward et al.,Nature 341,544-546(1989)),它主要由VH结构域组成;(vi)独立的互补决定区(CDR)1,及(vii)两个或单个独立的CDRs的组合,可选择性地通过合成的连接物连接。另外,虽然Fv片段、VL和VH的两个结构域是由不同的基因编码的,但他们可通过重组方法,用可使其VL 和VH区形成单价分子而作为单个蛋白链的合成的连接物连接(已知作为单链抗体或单链Fv(scFv),参见例如,Bird et al.,Science 242,423-426(1988)and Hustonet al.,PNAS USA 85,5879-5883(1988))。这种单链抗体在术语抗体的范围内,除非文中特别说明或明确提示。其它类型的单链抗体,例如双功能抗体包括在术语抗体的范围内。虽然这种片段通常包括在抗体的含义中,但它们所有每个都是本发明的独特特征,表现不同的生物学特性和用途。这些和其它有用的抗体片段在本文进一步讨论。As noted above, unless otherwise stated or clearly contradicted by context, the term antibody herein includes that portion of an antibody that has the ability to specifically bind an antigen. It has been shown that the antigen-binding function of antibodies can be performed by fragments of full-length antibodies. Examples of binding fragments included within the term "antibody" include (i) Fab fragments, monovalent fragments containing VL , VH , CL and CH1 domains; (ii) F(ab) 2 and F(ab ') 2 fragments, a bivalent fragment containing 2 Fab fragments connected by disulfide bonds at the hinge region; (iii) Fd fragment mainly composed of VH and CH1 domains; (iv) mainly composed of a single antibody fragment Fv fragment composed of the V L and V H domains of the arm; (v) dAb fragment (Ward et al., Nature 341, 544-546 (1989)), which is mainly composed of the V H domain; (vi) independent The complementarity determining region (CDR) 1, and (vii) a combination of two or single individual CDRs, optionally joined by a synthetic linker. In addition, although the two structural domains of the Fv fragment, V L and V H , are encoded by different genes, they can be used as a single protein chain by recombination methods that allow their V L and V H regions to form monovalent molecules. Synthetic linker ligation (known as single-chain antibody or single-chain Fv (scFv), see, for example, Bird et al., Science 242, 423-426 (1988) and Hustone et al., PNAS USA 85, 5879-5883 ( 1988)). Such single chain antibodies are within the scope of the term antibody unless otherwise specified or explicitly suggested by the context. Other types of single chain antibodies, such as diabodies are included within the scope of the term antibody. While such fragments are generally included within the meaning of antibodies, each of them is a unique feature of the invention, exhibiting different biological properties and uses. These and other useful antibody fragments are discussed further herein.
也应理解术语抗体也通常包括多克隆抗体、单克隆抗体(mAbs),抗体类似的多肽,例如通过任何已知技术,例如酶切割、肽合成和重组技术制备的嵌合抗体和人源化抗体,抗体的抗独特型(抗Id)抗体和具有与抗原特异结合的能力的抗体片段(抗原结合片段)。产生的抗体具有任何同种型。It is also understood that the term antibody also generally includes polyclonal antibodies, monoclonal antibodies (mAbs), antibody-like polypeptides, such as chimeric and humanized antibodies prepared by any known technique, such as enzymatic cleavage, peptide synthesis and recombinant techniques , anti-idiotypic (anti-Id) antibodies of antibodies and antibody fragments (antigen-binding fragments) having the ability to specifically bind to an antigen. Antibodies produced can be of any isotype.
抗CD38抗体是如上所述的抗体,它可与抗原CD38特异结合。An anti-CD38 antibody is an antibody as described above that specifically binds to the antigen CD38.
术语“抗原决定簇”是指可与抗体特异结合的蛋白决定区。抗原决定簇通常由分子的有化学活性的表面基团,例如氨基酸或糖侧链组成,通常具有特定的3个二维结构特征,及特定的电荷特征。可区分构象和非构象抗原决定簇,因为在存在变性溶剂时,前者的结合消失,而后者的结合不消失。抗原决定簇可含有直接参与结合的氨基酸残基(也称为 抗原决定簇的免疫优势组分)和其它氨基酸残基,它们不直接参与结合,例如通过特异的抗原结合肽而被有效封闭的氨基酸残基(即,氨基酸残基在特异的抗原结合肽的覆盖区)。The term "antigenic determinant" refers to a determinant region of a protein that can specifically bind to an antibody. Antigenic determinants usually consist of chemically active surface groups of molecules, such as amino acids or sugar side chains, and usually have specific three-dimensional structural characteristics and specific charge characteristics. A distinction can be made between conformational and non-conformational epitopes, since binding of the former but not the latter disappears in the presence of denaturing solvents. An antigenic determinant may contain amino acid residues that are directly involved in binding (also known as the immunodominant component of the epitope) and other amino acid residues that are not directly involved in binding, such as amino acids effectively blocked by specific antigen-binding peptides residues (ie, amino acid residues in the footprint of a specific antigen-binding peptide).
术语“双特异性分子”包括任何试剂,例如蛋白、肽和蛋白或肽的复合物,它具有两个不同的结合特异性。例如,该分子可与(a)细胞表面的抗原和(b)效应细胞编码的Fc受体结合或相互作用。术语“多特异性分子”包括任何试剂,例如蛋白、肽和蛋白或肽的复合物,它具有多于两个不同的结合特异性。例如,该分子可与(a)细胞表面的抗原,(b)效应细胞编码的Fc受体和(c)至少一种其它组分结合或相互作用。因此,本发明包括,但不限定于,针对CD3 8和其它细胞表面抗原或靶,例如效应细胞的Fc受体的双特异性、三特异性、四特异性和其它多特异性分子。The term "bispecific molecule" includes any agent, such as a protein, a peptide, and a complex of proteins or peptides, which has two different binding specificities. For example, the molecule can bind or interact with (a) an antigen on the cell surface and (b) an Fc receptor encoded by an effector cell. The term "multispecific molecule" includes any agent, such as proteins, peptides and complexes of proteins or peptides, which has more than two different binding specificities. For example, the molecule can bind or interact with (a) an antigen on the cell surface, (b) an Fc receptor encoded by an effector cell, and (c) at least one other component. Thus, the invention includes, but is not limited to, bispecific, trispecific, tetraspecific and other multispecific molecules directed against CD38 and other cell surface antigens or targets, such as Fc receptors of effector cells.
术语“双特异性抗体”包括任何双特异性分子的抗CD38抗体。术语“双特异性抗体”也包括双功能抗体。双功能抗体是二价的双特异性抗体,其中VH和VL结构域在单个多肽链上表达,但通过同一链上的两个结构域间的较短的不能使其配对的连接物进行连接,从而使结构域与另一条链的互补结构域配对,从而得到两个抗原结合位点(参见,例如Holliger,P.et al.,PNAS USA 90,6444-6448(1993)、Poljak,RJ.et al.,Structure 2,1121-1123(1994))。The term "bispecific antibody" includes anti-CD38 antibodies of any bispecific molecule. The term "bispecific antibody" also includes bifunctional antibodies. Diabodies are bivalent, bispecific antibodies in which the VH and VL domains are expressed on a single polypeptide chain, but through a shorter linker between the two domains on the same chain that does not enable their pairing. Linking such that the domains are paired with complementary domains of another chain, resulting in two antigen-binding sites (see, e.g., Holliger, P. et al., PNAS USA 90, 6444-6448 (1993), Poljak, RJ et al., Structure 2, 1121-1123 (1994)).
此处所用术语“效应细胞”是指参与免疫应答的效应阶段的免疫细胞,与免疫应答的认知和激活阶段相对应。示例的免疫细胞包括骨髓或淋巴来源的细胞,例如,淋巴细胞(例如B细胞和T细胞,包括溶细胞的T细胞(CTLs)),杀伤细胞、自然杀伤细胞、巨噬细胞、单核细胞、嗜曙红细胞、嗜中性粒细胞、分叶核白细胞、粒细胞、肥大细胞和嗜碱细胞。某些效应细胞表达特异的Fc受体,并具有特定的免疫功能。在某些技术方案中,效应细胞可诱导抗体依赖的细胞毒素作用(ADCC),例如嗜中性粒细胞可诱导ADCC。例如,表达FcR的单核细胞、巨噬细胞参与特定的靶细胞杀伤,并向免疫系统的其它组分呈递抗原,或与呈递抗原的细胞结合。在某些技术方案中,效应细胞可吞噬靶抗原、靶细胞或微生物。效应细胞上特定的FcR的表达可通过体液因子,例如细胞因子来调控。例如,已发现FcγRI的表达可被干扰素γ(IFN-γ)和/或G-CSF上调。这种增强的表达可提高含FcγRI的细胞针对靶的细胞毒活性。效应细胞可吞噬或裂解靶抗原或靶细胞。The term "effector cells" as used herein refers to immune cells that participate in the effector phase of an immune response, corresponding to the cognitive and activation phases of the immune response. Exemplary immune cells include cells of myeloid or lymphoid origin, e.g., lymphocytes (e.g., B cells and T cells, including cytolytic T cells (CTLs)), killer cells, natural killer cells, macrophages, monocytes, Eosinophils, neutrophils, segmented leukocytes, granulocytes, mast cells, and basophils. Certain effector cells express specific Fc receptors and have specific immune functions. In certain embodiments, the effector cells induce antibody-dependent cytotoxicity (ADCC), eg, neutrophils induce ADCC. For example, FcR-expressing monocytes, macrophages participate in specific target cell killing, and present antigens to other components of the immune system, or bind to cells presenting antigens. In some embodiments, the effector cells can phagocytose target antigens, target cells or microorganisms. The expression of specific FcRs on effector cells can be regulated by humoral factors, such as cytokines. For example, it has been found that the expression of FcγRI can be upregulated by interferon gamma (IFN-γ) and/or G-CSF. This enhanced expression increases the cytotoxic activity of FcyRI-containing cells against targets. Effector cells can phagocytose or lyse target antigens or target cells.
此处所用术语“人抗体”包括具有来源于人胚系免疫球蛋白序列的可变区和恒定区的抗体。本发明的人抗体也包括不被人胚系免疫球蛋白序列编码的氨基酸残基(例如,通过体外随机或定点突变或体内细胞突变引入的突变)。但此处所用术语“人抗体”不包括其来源于其它哺乳动物种,例如鼠的CDR序列移植到人的阅读框序列中的抗体。此处所用人抗体是“来源于”特定的胚系序列,如果抗体是从使用人免疫球蛋白序列的系统,例如通过免疫携带人免疫球蛋白基因的转基因鼠,或通过筛选人免疫球蛋白基因库而获得的,则筛选的人抗体的氨基酸序列与由胚系VH或VL可变区基因片段编码的氨基酸序列的同一性至少为90%,例如至少为95%,例如至少为96%,例如至少为97%,例如至少为98%,或例如至少为99%。典型地,来源于特定的人胚系VH或VL 可变区基因片段序列的人抗体与由胚系免疫球蛋白基因编码的氨基酸序列相比较,具有不超过10个氨基酸的差异,例如不超过5,例如不超过4、3、2或1个氨基酸差异。The term "human antibody" as used herein includes antibodies having variable and constant regions derived from human germline immunoglobulin sequences. The human antibodies of the invention also include amino acid residues not encoded by human germline immunoglobulin sequences (eg, mutations introduced by random or site-directed mutagenesis in vitro or cellular mutation in vivo). However, the term "human antibody" as used herein does not include antibodies whose CDR sequences derived from other mammalian species, such as mice, are grafted into human reading frame sequences. A human antibody as used herein is "derived" from a particular germline sequence if the antibody is obtained from a system using human immunoglobulin sequences, for example by immunization of transgenic mice carrying human immunoglobulin genes, or by screening human immunoglobulin gene repertoires If obtained, the amino acid sequence of the screened human antibody is at least 90%, such as at least 95%, such as at least 96%, identical to the amino acid sequence encoded by the germline VH or VL variable region gene segment, For example at least 97%, such as at least 98%, or such as at least 99%. Typically, a human antibody derived from a specific human germline VH or VL variable region gene sequence differs by no more than 10 amino acids from the amino acid sequence encoded by a germline immunoglobulin gene, e.g., no More than 5, such as no more than 4, 3, 2 or 1 amino acid difference.
嵌合抗体是含有一个或多个来源于一个抗体的区域和一个或多个来源于一个或多个来自另一个物种的其它抗体的区域的抗体。单价嵌合抗体是将嵌合的H链通过二硫键与嵌合的L链连接而形成的二聚体(HL))。二价嵌合抗体是两个HL二聚体通过至少一个二硫键连接而形成的四聚体(H2L2)。也可产生多价嵌合抗体,例如,通过使CH区寡聚化(例如来源于IgM H链或μ链)。典型地,嵌合抗体是指其重链和/或轻链部分与来源于特定物种的抗体的对应序列同一或同源的或属于特定的抗体类型或亚类,而链的其余部分与另一物种的抗体的对应序列同一或同源或属于另一种抗体类型或亚类的抗体及这种抗体的片段,只要它们具有所需的生物活性即可(参见,例如US 4,816,567和Morrison et al.,PNAS USA 81.,6851-6855(1984))。嵌合抗体通过本领域已知的重组过程产生(参见,例如Cabilly etal.,PNAS USA 81,3273-3277(1984)、Morrison et al.,PNAS USA 8JL 6851-6855(1984)、Boulianne et al.,Nature 312,643-646(1984)、EP 125023,Neuberger etal.,Nature314,268-270(1985)、EP 171496,EP173494、WO86/01533,EP 184187,Sahagan et al.,J.Immunol.137.1066-1074(1986)、WO87/02671,Liu et al.,PNAS USA 84,3439-3443(1987)、Sun et al., PNAS USA 84,214-218(1987)、Better et al.,Science 240,1041-1043(1988)and Harlow et al.,Antibodies:A Laboratory Manual,Cold SpringHarborLaboratory Press,Cold Spring Harbor,N.Y.,(1988))。Chimeric antibodies are antibodies that contain one or more regions derived from one antibody and one or more regions derived from one or more other antibodies from another species. A monovalent chimeric antibody is a dimer (HL) formed by linking a chimeric H chain and a chimeric L chain through a disulfide bond. Bivalent chimeric antibodies are tetramers ( H2L2 ) of two HL dimers linked by at least one disulfide bond. Multivalent chimeric antibodies can also be produced, for example, by oligomerization of the CH region (eg, derived from IgM H chain or μ chain). Typically, a chimeric antibody refers to a heavy chain and/or light chain portion of which is identical or homologous to the corresponding sequence of an antibody derived from a specific species or belongs to a specific antibody type or subclass, while the rest of the chain is identical to another Species identical or homologous to the corresponding sequence of an antibody or belonging to another antibody type or subclass, and fragments of such antibodies, so long as they possess the desired biological activity (see, for example, US 4,816,567 and Morrison et al. , PNAS USA 81., 6851-6855 (1984)). Chimeric antibodies are produced by recombinant procedures known in the art (see, e.g., Cabilly et al., PNAS USA 81, 3273-3277 (1984), Morrison et al., PNAS USA 8JL 6851-6855 (1984), Boulianne et al. , Nature 312,643-646 (1984), EP 125023, Neuberger et al., Nature 314, 268-270 (1985), EP 171496, EP173494, WO86/01533, EP 184187, Sahagan et al., J.Immunol.137.1066- 1074(1986), WO87/02671, Liu et al., PNAS USA 84, 3439-3443(1987), Sun et al., PNAS USA 84, 214-218(1987), Better et al., Science 240, 1041 -1043 (1988) and Harlow et al., Antibodies: A Laboratory Manual, Cold Spring Harbor Laboratory Press, Cold Spring Harbor, NY, (1988)).
人源化抗体是来源于非人物种的抗体,其中将阅读框和重链及轻链恒定区的特定氨基酸突变,从而可避免或消除在人中的免疫应答。非人(例如鼠)抗体的人源化形式是含有来源于非人免疫球蛋白最小序列的嵌合抗体。对大部分而言,人源化抗体是其受体的高变区残基被具有所需抗原结合特性,例如特异性和亲和性的非人物种(供体抗体),例如小鼠、大鼠、兔或非人灵长类的高变区残基替代的人免疫球蛋白(受体抗体)。在某些情况下,人免疫球蛋白的Fv阅读框区域(FR)残基被相应的非人残基替代。另外,人源化抗体可含有受体抗体或供体抗体中没有的残基。这些修饰可进一步优化抗体的功能。通常,人源化抗体实质含有至少一个,典型地两个可变结构域,其中所有或实质所有高变区的环对应非人免疫球蛋白,或所有或实质所有FR区域是人免疫球蛋白的序列。人源化抗体选择性地也含有至少一部分免疫球蛋白的恒定区(Fc),典型地是人免疫球蛋白的恒定区。详细内容参见Jones et al.,Nature 321,522-525(1986)、Riechmann et al.,Nature 332,323-329(1988)and Presta,Curr.Op.Struct.Biol.2,593-596(1992)。Humanized antibodies are antibodies derived from a non-human species in which specific amino acids in the reading frame and constant regions of the heavy and light chains have been mutated so that an immune response in humans can be avoided or eliminated. Humanized forms of non-human (eg, murine) antibodies are chimeric antibodies that contain minimal sequence derived from non-human immunoglobulin. For the most part, a humanized antibody is a non-human species (donor antibody) whose recipient hypervariable region residues have been modified to possess the desired antigen-binding properties, such as specificity and affinity (donor antibody), such as mouse, rat Human immunoglobulin (recipient antibody) substituted with hypervariable region residues from , rabbit or non-human primate. In certain instances, Fv reading frame region (FR) residues of the human immunoglobulin are replaced by corresponding non-human residues. In addition, humanized antibodies can contain residues that are not found in either the recipient antibody or the donor antibody. These modifications can further optimize the function of the antibody. In general, humanized antibodies contain substantially at least one, typically two, variable domains in which all or substantially all of the loops of the hypervariable regions correspond to non-human immunoglobulins, or in which all or substantially all FR regions are of human immunoglobulins sequence. A humanized antibody optionally also will contain at least a portion of an immunoglobulin constant region (Fc), typically that of a human immunoglobulin. For details, see Jones et al., Nature 321, 522-525 (1986), Riechmann et al., Nature 332, 323-329 (1988) and Presta, Curr.Op.Struct.Biol.2, 593-596 (1992 ).
此处所用“单克隆抗体”或“单克隆抗体组分”是指单分子组分的抗体分子的制备。单克隆抗体组分具有单一的特定抗原决定簇的结合特异性和亲和性。因此,术语“人单克隆抗体”是指具有来源于人胚系免疫球蛋白序列的可变区和恒定区,并具有单一的结合特异性的抗体。人单克隆抗体可通过杂交瘤产生,包括从具有包含人重链转基因和轻链转基因的基因组的转基因或转染色体非人动物,例如转基因鼠获得B细胞与永生化细胞融合。单克隆抗体可缩写为mAb。As used herein, "monoclonal antibody" or "monoclonal antibody composition" refers to the preparation of antibody molecules of single molecular composition. Monoclonal antibody components have a single binding specificity and affinity for a particular antigenic determinant. Thus, the term "human monoclonal antibody" refers to an antibody having variable and constant regions derived from human germline immunoglobulin sequences and having a single binding specificity. Human monoclonal antibodies can be produced by hybridomas, including the fusion of B cells obtained from a transgenic or transchromosomal non-human animal, such as a transgenic mouse, with a genome comprising a human heavy chain transgene and a light chain transgene, with immortalized cells. A monoclonal antibody may be abbreviated as mAb.
此处所用术语“重组人抗体”包括所有通过重组方法制备、表达、产生或分离的人抗体,例如(a)从含有人免疫球蛋白基因的转基因或转染色体动物(例如鼠)中分离的抗体或制备的杂交瘤(在本文其它部分描述),(b)从转化的以表达抗体的宿主细胞,例如转染瘤分离的抗体,(c)从重组的、组合人抗体库分离的抗体,及(d)通过任何其它涉及将人免疫球蛋白基因序列与其它DNA序列拼接的方法制备、表达、产生或分离的抗体。这种重组的人抗体具有来源于人胚系免疫球蛋 白序列的可变区和恒定区。但在某些技术方案中,这种重组人抗体可进行体外突变(或当对人Ig序列使用动物转基因时,为体内体细胞突变),因此,重组抗体的VH和VL区的氨基酸序列,当它们来源于人胚系VH 和VL序列并与之相关时,可以是体内人抗体胚系库天然不存在的序列。The term "recombinant human antibody" as used herein includes all human antibodies prepared, expressed, produced or isolated by recombinant methods, for example (a) antibodies isolated from transgenic or transchromosomal animals (such as murines) containing human immunoglobulin genes or prepared hybridomas (described elsewhere herein), (b) antibodies isolated from host cells transformed to express antibodies, such as transfectomas, (c) antibodies isolated from recombinant, combinatorial human antibody repertoires, and (d) Antibodies prepared, expressed, produced or isolated by any other method involving the splicing of human immunoglobulin gene sequences with other DNA sequences. Such recombinant human antibodies have variable and constant regions derived from human germline immunoglobulin sequences. However, in some technical schemes, this recombinant human antibody can undergo in vitro mutation (or in vivo somatic mutation when animal transgenes are used for human Ig sequences), therefore, the amino acid sequences of the VH and VL regions of the recombinant antibody , when derived from and related to human germline VH and VL sequences, may be sequences that do not naturally occur in the human antibody germline repertoire in vivo.
此处所用“异源抗体”定义为涉及转基因非人生物产生的抗体。该术语是指与在不由非人动物所组成的生物中,通常是在来源于除了转基因非人动物外的某个物种中所发现的抗体具有相对应的氨基酸序列的抗体。"Heterologous antibody" as used herein is defined to refer to antibodies produced by a genetically modified non-human organism. The term refers to an antibody that has an amino acid sequence corresponding to an antibody found in an organism that does not consist of a non-human animal, usually a species derived from a species other than a transgenic non-human animal.
此处所用“分离的抗体”是指实质不含有其它具有不同的抗原特异性的抗体(例如,与CD38特异结合的分离抗体实质不含有与除CD38外的抗原特异结合的抗体)的抗体。但与人CD38的抗原决定簇、同种型或变异体特异结合的分离抗体可与其它相关的抗原,例如来源于其它物种(例如CD38物种同源体)具有交叉反应性。另外,分离抗体实质不含有其它细胞物质和/和化学制品。在本发明的一个技术方案中,具有不同特异性的“分离的”单克隆抗体的组合可含有明确的成分。As used herein, "isolated antibody" refers to an antibody that is substantially free of other antibodies with different antigen specificities (eg, an isolated antibody that specifically binds to CD38 does not contain substantially antibodies that specifically bind to antigens other than CD38). However, an isolated antibody that specifically binds to an epitope, isoform or variant of human CD38 may have cross-reactivity with other related antigens, eg, from other species (eg CD38 species homologues). Additionally, an isolated antibody is substantially free of other cellular material and/and chemicals. In one embodiment of the invention, the combination of "isolated" monoclonal antibodies with different specificities may contain distinct components.
此处所用“特异结合”是指诸如抗体这样的抗原结合肽,结合到预定的抗原上。典型地,当通过表面等离子共振(SPR)技术在BIAcore 3000仪器上,以重组CD38为配体,抗体为分析物进行测定时,诸如抗体这样的抗原结合肽的结合亲和性相当于KD为10-7M或更少,例如约10-8M或更少,例如约10-9M或更少,约10-10M或更少,约10-11M或更少。抗原结合肽可与预定抗原以相当于的KD,比其与除预定蛋白或密切相关的抗原之外的非特异抗原(例如BSA、酪蛋白)的结合亲和性低至少10倍,例如至少低100倍,例如至少低1000倍,例如至少低10,000倍,例如至少低1000,000倍的亲和力结合。具有更低的亲和力的量依赖于抗原结合肽的KD,因此当抗原结合肽的KD很低时(即抗原结合肽是高度特异的),则与抗原亲和力的量比与非特异抗原亲和力至少低10,000倍。此处所用短语“识别抗原的抗原结合肽”和“抗原特异的抗原结合肽”可与术语“与抗原特异结合的抗原结合肽”互换使用。同样,此处所用短语“识别抗原的抗体”和“抗原特异的抗体”可与术语“与抗原特异结合的抗体”互换使用。As used herein, "specifically binds" means that an antigen-binding peptide, such as an antibody, binds to a predetermined antigen. Typically, an antigen-binding peptide such as an antibody has a binding affinity equivalent to a K of 10 −7 M or less, such as about 10 −8 M or less, such as about 10 −9 M or less, about 10 −10 M or less, about 10 −11 M or less. The antigen-binding peptide may bind to the intended antigen with an equivalent KD that is at least 10-fold lower than its binding affinity to non-specific antigens (e.g., BSA, casein) other than the intended protein or closely related antigens, e.g., at least 100-fold lower, such as at least 1000-fold lower, such as at least 10,000-fold lower, such as at least 1000,000-fold lower affinity binding. Quantities with lower affinities are dependent on the KD of the antigen-binding peptide, so when the KD of the antigen-binding peptide is low (i.e., the antigen-binding peptide is highly specific), then the quantity with affinity for the antigen is more specific than the quantity with affinity for the non-specific antigen At least 10,000 times lower. As used herein, the phrases "antigen-binding peptide that recognizes an antigen" and "antigen-specific antigen-binding peptide" are used interchangeably with the term "antigen-binding peptide that specifically binds to an antigen." Also, as used herein, the phrases "antibody that recognizes an antigen" and "antigen-specific antibody" are used interchangeably with the term "antibody that specifically binds an antigen."
此处所用术语“kd”(sec-1)是指特定的抗体抗原相互作用的解离平衡速率常数。所述值也指koff值。The term "k d " (sec -1 ) as used herein refers to the dissociation equilibrium rate constant for a particular antibody-antigen interaction. Said values are also referred to as k off values.
此处所用术语“ka”(M-1×sec-1)是指特定的抗体抗原相互作用的结合平衡速率常数。The term " ka " (M -1 xsec -1 ) as used herein refers to the equilibrium rate constant for binding of a particular antibody-antigen interaction.
此处所用术语“kD”(M)是指特定的抗体抗原相互作用的解离平衡常数。The term " kD " (M) as used herein refers to the dissociation equilibrium constant for a particular antibody-antigen interaction.
此处所用术语“KA”(M-1)是指特定的抗体抗原相互作用的结合平衡常数,通过ka除以kd而得到。The term "KA" ( M -1 ) as used herein refers to the binding equilibrium constant for a particular antibody-antigen interaction, obtained by dividing ka by kd .
此处所用“同种型”是指由重链恒定区基因编码的抗体类型(例如IgG1、IgG2、IgG3、IgG4、IgD、IgA、IgE、或IgM)。"Isotype" as used herein refers to the antibody class (eg, IgGl, IgG2, IgG3, IgG4, IgD, IgA, IgE, or IgM) encoded by the heavy chain constant region genes.
此处所用“同种型转换”是指抗体的类型或同种型从一种免疫球蛋白类型转变为一种其它的免疫球蛋白类型的现象。"Isotype switching" as used herein refers to the phenomenon in which the class or isotype of an antibody changes from one immunoglobulin class to another.
此处所用“非转换的同种型”是指在无同种型转换发生时产生的重链的同种型类型;编码非转换同种型的CH基因典型地是紧接功能性重组VDJ基因下游的第一个CH基因。同种型转换分为典型的或非典型的同种型转换。典型的同种型转换通过至少转基因的一个转换序列区参与的重组事件发生。非典型的同种型转换可发生在例如人σμ和人∑μ(δ-相关的缺失)间的同源重组。选择性的非典型转换机制,例如转基因内和/或染色体内重组可发生,并实现同种型转换。"Non-switched isoform" as used herein refers to the isotype type of the heavy chain produced when no isotype switching occurs; the CH gene encoding the non-switched isoform is typically followed by a functionally recombinant VDJ gene The first CH gene downstream. Isotype switching is classified as typical or atypical isotype switching. Typically isotype switching occurs through recombination events involving at least one switch sequence region of the transgene. Atypical isotype switching can occur, for example, by homologous recombination between human σμ and human Σμ (δ-associated deletion). Alternative atypical switching mechanisms such as intra-transgenic and/or intra-chromosomal recombination can occur and achieve isotype switching.
此处所用术语“转换序列”是指那些负责转换重组的DNA序列。“转换供体”序列典型地是μ转换区,是在转换重组过程中被删除的恒定区的5′(即上游)。“转换受体”区是被删除的恒定区和替代的恒定区(例如γ、ε等)之间。由于在发生重组的地方没有特定的位点,因此典型地,最终的基因序列不能从构建体来预测。The term "switch sequence" as used herein refers to those DNA sequences responsible for switch recombination. The "switch donor" sequence is typically the mu switch region, 5' (ie, upstream) of the constant region that is deleted during switch recombination. A "switch acceptor" region is between the deleted constant region and the replacement constant region (eg gamma, epsilon, etc.). Since there is no specific site where recombination occurs, typically the final gene sequence cannot be predicted from the construct.
此处所用“糖基化模式”定义为与蛋白,更具体地与免疫球蛋白(抗体)蛋白共价连接的碳水化合物单元的模式。异源抗体的糖基化模式的特征在于与由非人转基因动物物种产生的抗体上天然存在的糖基化模式实质上是相似的,本领域普通人员会意识到异源抗体的糖基化模式与所述非人转基因动物物种的糖基化模式比与转基因的CH基因来源的物种具有更大的相似性。As used herein, "glycosylation pattern" is defined as the pattern of carbohydrate units covalently attached to proteins, more specifically to immunoglobulin (antibody) proteins. The glycosylation pattern of the heterologous antibody is characterized by being substantially similar to the glycosylation pattern naturally occurring on the antibody produced by the non-human transgenic animal species, and those of ordinary skill in the art will recognize the glycosylation pattern of the heterologous antibody The glycosylation pattern is more similar to the species of the non-human transgenic animal than to the species from which the transgenic CH gene was derived.
此处所用术语“天然存在的”用于某受试体时是指该受试体是在自然界发现的。例如,可从自然界来源分离的,没有在实验室人工改变的生物(包括病毒)中存在的多肽或多聚核酸序列是天然存在的。As used herein, the term "naturally occurring" when applied to a subject means that the subject is found in nature. For example, a polypeptide or polynucleic acid sequence that is isolated from a natural source and that is not found in laboratory-modified organisms, including viruses, is naturally occurring.
此处所用术语“重排的”是指重链或轻链免疫球蛋白座位的构象, 其中在分别编码完整的VH或VL结构域的构象中,V片段位于紧邻D-J或J片段。重组的免疫球蛋白(抗体)基因座位可通过与胚系DNA比较来鉴定;重组的座位具有至少一个七聚物/九聚物同源元件。The term "rearranged" as used herein refers to a conformation of a heavy or light chain immunoglobulin locus wherein the V segment is located immediately adjacent to the DJ or J segment in a conformation encoding a complete VH or VL domain, respectively. Recombined immunoglobulin (antibody) gene loci can be identified by comparison to germline DNA; recombinant loci have at least one heptamer/nonamer homologous element.
此处所用术语“未重排的”或“胚系构象”参照V片段而言,是指其中V片段不重组以与D或J片段紧邻的构象。The term "unrearranged" or "germline conformation" as used herein with reference to the V segment refers to a conformation in which the V segment does not recombine to be in close proximity to the D or J segment.
此处所用术语“核酸分子”是指DNA分子和RNA分子。核酸分子可以是单链的或双链的,但优选地是双链DNA。核酸可存在于全细胞、细胞裂解物中或是部分纯化或基本纯化的形式。The term "nucleic acid molecule" as used herein refers to DNA molecules and RNA molecules. Nucleic acid molecules can be single-stranded or double-stranded, but are preferably double-stranded DNA. Nucleic acids may be present in whole cells, cell lysates, or in partially or substantially purified form.
当通过标准技术,包括碱/SDS处理、CsCl成带、柱色谱、琼脂糖凝胶电泳和其它本领域公知的技术从其它细胞成分或诸如其它细胞核酸或蛋白等其它污染物中将核酸纯化出来时,在核酸是“分离的”或“基本纯化的”。参见F.Ausubel et al.,ed.CurrentProtocols in MolecularBiology,Greene Publishing and Wiley InterScience NewYork(1987)。When the nucleic acid is purified from other cellular components or other contaminants such as other cellular nucleic acids or proteins by standard techniques including alkali/SDS treatment, CsCl banding, column chromatography, agarose gel electrophoresis and other techniques known in the art When the nucleic acid is "isolated" or "substantially purified". See F. Ausubel et al., ed. Current Protocols in Molecular Biology, Greene Publishing and Wiley InterScience New York (1987).
当将其与另一个核酸序列进行功能相连时,则核酸是“可操作连接的”。例如,启动子或增强子当影响序列的转录时则是与编码序列可操作连接的。对于调控序列的转录而言,可操作连接是指被连接的DNA序列在连接两个蛋白编码区是连续的,而且使阅读框也是连续的。对开关序列而言,可操作连接表示可影响开关重组的序列。Nucleic acids are "operably linked" when they are functionally linked to another nucleic acid sequence. For example, a promoter or enhancer is operably linked to a coding sequence when it affects the transcription of the sequence. For the transcription of regulatory sequences, operably linked means that the DNA sequences being linked are contiguous in connecting two protein coding regions, and the reading frames are also contiguous. With respect to switch sequences, operably linked means sequences that can affect switch recombination.
此处所用术语“抑制生长”(例如当指细胞时)是指当与CD38BP,例如抗CD38抗体接触时,和未与CD38BP,例如抗CD38抗体接触时相比较,细胞生长的任何可测定的降低,例如抑制细胞培养物生长的至少约10%、20%、30%、40%、50%、60%、70%、80%、90%、99%或100%。The term "growth inhibition" (e.g. when referring to cells) as used herein refers to any measurable decrease in cell growth when contacted with a CD38BP, e.g., an anti-CD38 antibody, compared to when not contacted with a CD38BP, e.g., an anti-CD38 antibody , such as inhibiting the growth of a cell culture by at least about 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 99%, or 100%.

Inhibition/blocking of the binding of the CD38 binder to CD38 can reduce or alter the normal level or type of cellular signaling that occurs when the binding of the CD38 binder to CD38 is not inhibited or blocked. Inhibition and blocking also refer to any measurable decrease in the binding affinity of a CD38 binder to CD38 when contacted with a CD38BP, such as an anti-CD38 antibody, compared to a ligand that is not contacted with a CD38BP, such as an anti-CD38 antibody , such as inhibiting the binding of a CD38-conjugate to CD38 by at least about 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 99%, or 100%.

此处所用术语“载体”是指可运输与其连接的另一种核酸的核酸分子。一种类型的载体是“质粒”,它是指环状双链DNA环,其中可连接额外的DNA片段。另一种类型的载体是病毒载体,其中额外的DNA片段可连接到病毒基因组中。某些载体可在其所导入的宿主细胞中自主复制(例如具有细菌复制起点的细菌载体和游离的哺乳动物载体)。其它载体(例如非游离哺乳动物载体)可在导入到宿主细胞后整合到宿主细胞的基因组中,然后与宿主基因组一起复制。此外,某些载体可指导与其可操作连接的基因的表达。这类载体在此处被称为“重组表达载体”(或简言之,“表达载体”)。一般来说,应用于重组DNA技术中的表达载体通常是质粒形式。在本说明书中,由于质粒是载体的最普遍的使用形式,因此“质粒”和“载体”可互换使用。但本发明包括其它形式的表达载体,例如病毒载体(比如复制缺陷的逆转录病毒、腺病毒和腺相关病毒,它们可发挥同样的功能。The term "vector" as used herein refers to a nucleic acid molecule capable of transporting another nucleic acid to which it has been linked. One type of vector is a "plasmid", which refers to a circular double-stranded DNA loop into which additional DNA segments can be ligated. Another type of vector is a viral vector, in which additional DNA segments can be ligated into the viral genome. Certain vectors replicate autonomously in the host cell into which they are introduced (eg, bacterial vectors with a bacterial origin of replication and episomal mammalian vectors). Other vectors (eg, non-episomal mammalian vectors) can integrate into the genome of the host cell after introduction into the host cell and then replicate with the host genome. In addition, certain vectors direct the expression of genes to which they are operably linked. Such vectors are referred to herein as "recombinant expression vectors" (or, simply, "expression vectors"). In general, expression vectors used in recombinant DNA techniques are usually in the form of plasmids. In this specification, "plasmid" and "vector" are used interchangeably since plasmid is the most commonly used form of vector. However, the invention includes other forms of expression vectors, such as viral vectors (such as replication defective retroviruses, adenoviruses and adeno-associated viruses), which serve the same function.
此处所用术语“重组宿主细胞”(或简言之“宿主细胞”)是指导入重组表达载体的细胞。可理解为该术语不仅是指特定的受试细胞,而且也指这种细胞的后代。由于在后代中因突变或环境影响可能发生某些 改变,因此事实上,这种后代可能与母细胞不是相同的,但仍包括在此处所用术语“宿主细胞”的范围中。重组宿主细胞包括例如诸如CHO细胞这样的转染瘤,NS/0细胞和淋巴细胞。The term "recombinant host cell" (or simply "host cell") as used herein refers to a cell into which a recombinant expression vector has been introduced. It is understood that the term refers not only to the particular subject cell, but also to the progeny of such a cell. Such progeny may not in fact be identical to the parent cell due to certain changes that may occur in the progeny due to mutations or environmental influences, but are still included within the scope of the term "host cell" as used herein. Recombinant host cells include, for example, transfectomas such as CHO cells, NS/0 cells and lymphocytes.
术语“调控序列”包括可控制抗体链基因转录或翻译的启动子、增强子和其它表达控制元件(例如多聚腺苷酸信号)。这种调控序列可描述在例如Goeddel,Gene ExpressionTechnology.Methods in Enzymology185,Academic Press,San Diego,Calif.(1990)中。本领域技术人员可设计表达载体,包括根据选择被转化的宿主细胞、所需蛋白的表达水平等因素来选择调控序列。用于哺乳动物宿主细胞表达的调控序列的例子包括可在哺乳动物中指导高水平蛋白表达的病毒元件,例如来源于]细胞巨化病毒(CMV)、猿病毒40(SV40)、腺病毒(例如腺病毒主要晚期启动子(AdMLP))和多瘤病毒的启动子和/或增强子。选择性地,可使用非病毒调控序列,例如泛素启动子β-球蛋白启动子。The term "regulatory sequence" includes promoters, enhancers and other expression control elements (eg, polyadenylation signals) that control the transcription or translation of the antibody chain genes. Such regulatory sequences are described, for example, in Goeddel, Gene Expression Technology. Methods in Enzymology 185, Academic Press, San Diego, Calif. (1990). Those skilled in the art can design expression vectors, including selection of regulatory sequences based on selection of transformed host cells, expression levels of desired proteins and other factors. Examples of regulatory sequences for expression in mammalian host cells include viral elements that direct high-level protein expression in mammals, such as those derived from cytomegalovirus (CMV), simian virus 40 (SV40), adenovirus (e.g. Adenovirus major late promoter (AdMLP)) and polyomavirus promoters and/or enhancers. Alternatively, non-viral regulatory sequences can be used, such as the ubiquitin promoter β-globin promoter.

术语“转基因非人动物”是指具有含一个或多个人重链和/或轻链转基因或转染色体的基因组(整合或不整合在动物的天然基因组DNA中),并可完全表达人抗体的非人动物。例如,转基因鼠可具有人轻链转基因或人重链转染色体,从而当鼠用CD38抗原和/或表达CD38的细胞免疫时可产生人可CD38抗体。人重链转基因可整合在鼠染色体DNA 中,这种情况下的转基因鼠是,例如诸如HCo7或HCo12鼠这样的HuMAb鼠,或人重链转基因可维持在染色体外,这种情况下的转染色体KM鼠在WO02/43478中有所描述。这种转基因和转染色体鼠(此处统称为“转基因鼠”)可通过V-D-J重组和同型体转换产生多种针对给定抗原的人单克隆抗体的同型体(例如IgG、IgA、IgM、IgD和/或IgE)。转基因非人动物也可通过导入编码特定抗体的基因、例如通过将基因与在动物乳汁中表达的基因有效连接的方式来用于产生针对特定抗原的抗体The term "transgenic non-human animal" refers to a non-human animal having a genome containing one or more human heavy and/or light chain transgenes or transchromosomes (integrated or not integrated into the animal's native genomic DNA) and capable of fully expressing human antibodies. human animal. For example, a transgenic mouse can have a human light chain transgene or a human heavy chain transchromosome so that when the mouse is immunized with a CD38 antigen and/or CD38-expressing cells, it can produce human CD38 antibodies. The human heavy chain transgene can be integrated in the mouse chromosomal DNA, in which case the transgenic mouse is, for example, a HuMAb mouse such as HCo7 or HCo12 mice, or the human heavy chain transgene can be maintained extrachromosomally, in which case the transchromosomal KM mice are described in WO02/43478. Such transgenic and transchromosomal mice (collectively referred to herein as "transgenic mice") can produce multiple isotypes (e.g., IgG, IgA, IgM, IgD, and and/or IgE). Transgenic non-human animals can also be used to produce antibodies to specific antigens by introducing a gene encoding the specific antibody, for example, by operably linking the gene to a gene expressed in the milk of the animal
此处所用术语特异性是指诸如抗CD38抗体这样的CD38结合肽识别CD38抗原决定簇、但对CD38的其它部分(包括可被诸如抗CD38抗体这样的其它CD38BPs结合的其它的抗原决定簇)仅具有很小或不可检测的反应性的能力。特异性可通过此处所述的竞争检测法进行相关检测。特异性更具体地可通过任何此处所述抗原决定簇鉴定/描述技术或其在本领域中已知的等效技术来测定。The term specificity as used herein means that a CD38 binding peptide, such as an anti-CD38 antibody, recognizes a CD38 epitope, but only to other parts of CD38 (including other epitopes that can be bound by other CD38BPs such as an anti-CD38 antibody).

Specificity may more specifically be determined by any of the antigenic determinant identification/characterization techniques described herein or their equivalent known in the art.
不过特异针对特定抗原决定簇的抗体可与某些存在CD38的生物样品中的其它分子发生交叉反应。更典型地,诸如抗CD38抗体这样的CD38BP,可与来自其它物种的CD38同源物交叉反应。在其中一种或全部两种情况下,典型地,这种交叉反应抗体是针对与人CD38相关的结构和/或环境因子进行选择的。However, antibodies specific for a particular epitope may cross-react with other molecules in some biological samples where CD38 is present. More typically, CD38BPs, such as anti-CD38 antibodies, cross-react with CD38 homologues from other species. In either or both cases, typically such cross-reactive antibodies are selected against structural and/or environmental factors associated with human CD38.
此处所用术语选择性是指诸如抗CD38抗体这样的CD38BP对特定的区域、靶、或者肽的优先结合;典型地,相对于一个或多个其它生物分子、结构、细胞、组织等,是CD38上的区域或抗原决定簇。在一个技术方案中,本发明中的诸如抗CD38抗体这样的CD38BP是针对直肠癌细胞环境中的CD38部分进行选择的(即,抗CD38抗体选择性地结合到CD38部分,超过与直肠癌细胞其它组分的结合)。The term selectivity as used herein refers to the preferential binding of a CD38BP, such as an anti-CD38 antibody, to a specific region, target, or peptide; typically, CD38 relative to one or more other biomolecules, structures, cells, tissues, etc. region or antigenic determinant.

An isolated molecule may also refer to any molecule obtained through a purification stage that has undergone human intervention, whether automated, manual or both. In the various compositions provided by the invention, for example, in the composition that contains one or more pharmaceutically acceptable carriers (for example, in the composition that contains a large amount of pharmaceutically acceptable carriers, stabilizers and/or preservatives case), CD38BP may be present in relatively small amounts depending on the number of all molecular species in the component. In some cases, additional peptides, such as BSA, can also be included in such fractions with previously purified CD38BP. However, such components can still be described as comprising isolated CD38BP if the additional composition of such components is acceptable for the intended use of CD38BP.
典型地,本发明的CD38BPs实质上不含有诸如具有不同抗原特异性的CD38BPs这样的其它CD38BPs。但本发明也提供了含有多种具有不同特异性和特征的CD38BPs的组分(例如,本发明提供了具有不同特异性和/或选择性特征的CD38BPs“鸡尾酒”)。Typically, the CD38BPs of the invention are substantially free of other CD38BPs such as CD38BPs with different antigenic specificities.

两个序列间的百分比同一性是序列中相同位点的数目的函数(即,%同源性=#一致位点/总#位点×100),为了对两个序列进行最适比对,需要考虑空位数目和每个空位的长度。可使用数学算法来实现两个序列间的序列比较和百分比同一性的测定,如下非限制性实施例所述。The percent identity between two sequences is a function of the number of identical positions in the sequences (i.e., % Homology = #identical positions/total # positions x 100), for optimal alignment of two sequences, The number of slots and the length of each slot need to be considered. The comparison of sequences and the determination of percent identity between two sequences can be accomplished using a mathematical algorithm, as described in the following non-limiting examples.
两个核苷酸序列间的百分比同一性可使用GCG软件包(可从 http://www.gcg.com获得)中的GAP程序,通过NWSgapdha.CMP矩阵和40、50、70或80的空位权重及1、2、3、4、5或6的长度权重来测定。两个核苷酸或氨基酸序列间的百分比同一性也可使用E.MeyersandW.Miller,Comput.Appl.Biosci 4,11-17(1988))中的算法来测定,它已整合到ALIGN程序(2.0版),所用的是PAM120权重残基表,空位长度罚分为12,空位罚分为4。另外,两个氨基酸序列间的百分比同一性可使用Needleman and Wunsch,J.MoI.Biol.48,444-453(1970))算法来测定,它已整合到GCG软件包(可从http://www.gcg.com获得)中的GAP程序中,使用的是Blossum 62矩阵和PAM250矩阵,空位权重为16、14、12、10、8、6或4,长度权重为1、2、3、4、5或6。The percent identity between two nucleotide sequences can be determined using the GAP program in the GCG software package (available from http://www.gcg.com ) by using the NWSgapdha.CMP matrix and gaps of 40, 50, 70 or 80 Weights and length weights of 1, 2, 3, 4, 5 or 6 are determined.

Biosci 4, 11-17 (1988)), which has been incorporated into the ALIGN program (2.0 version), the PAM120 weighted residue table was used, the gap length penalty was 12, and the gap penalty was 4. Alternatively, the percent identity between two amino acid sequences can be determined using the Needleman and Wunsch, J. MoI. Biol. 48, 444-453 (1970)) algorithm, which has been incorporated into the GCG software package (available from http:// In the GAP program obtained from www.gcg.com ), Blossum 62 matrix and PAM250 matrix are used, the gap weight is 16, 14, 12, 10, 8, 6 or 4, and the length weight is 1, 2, 3, 4 , 5 or 6.
本发明的核酸和蛋白序列可进一步用作“查询序列”,以对公共数据库进行搜索,例如鉴定相关序列。这种搜索可使用Altschul et al.,J.MoI.Biol.215,403-10(1990)NBLAST和XBLAST程序(2.0版)来执行。可使用NBLAST程序,分数=100,字长=12来执行BLAST核苷酸搜索,以获得与本发明中核酸分子同源的核苷酸序列。可使用XBLAST程序,分数=50,字长=3来执行BLAST蛋白搜索,以获得与本发明中蛋白分子同源的氨基酸序列。为了获得空位比对以进行比较,可使用如Altschulet al.,Nucleic Acids Res.25(17),3389-3402(1997)所述的GappedBLAST。当使用BLAST和Gapped BLAST程序时,可使用各自程序(例 如XBLAST和NBLAST)的缺省参数。参见http://www.ncbi.nlm.nih.gov。The nucleic acid and protein sequences of the invention can further be used as "query sequences" to perform searches against public databases, eg, to identify related sequences. Such searches can be performed using the NBLAST and XBLAST programs (version 2.0) of Altschul et al., J. MoI. Biol. 215, 403-10 (1990). BLAST nucleotide searches can be performed using the NBLAST program, score=100, wordlength=12 to obtain nucleotide sequences homologous to nucleic acid molecules of the invention. BLAST protein searches can be performed with the XBLAST program, score = 50, wordlength = 3 to obtain amino acid sequences homologous to protein molecules of the invention. To obtain gapped alignments for comparison, GappedBLAST as described by Altschule et al., Nucleic Acids Res. 25(17), 3389-3402 (1997) can be used. When utilizing BLAST and Gapped BLAST programs, the default parameters of the respective programs (eg, XBLAST and NBLAST) can be used. See http://www.ncbi.nlm.nih.gov .

In the context of the present invention, conservative substitutions are defined as substitutions in the amino acid classes indicated in one or more of the following 3 tables:
保守替代的氨基酸残基种类Conservatively substituted amino acid residues
可选择的保守氨基酸残基替代的种类Types of alternative conservative amino acid residue substitutions
更保守的替代组包括:缬氨酸-亮氨酸-异亮氨酸、苯丙氨酸-酪氨酸、赖氨酸-精氨酸、丙氨酸-缬氨酸和天冬氨酸-谷氨酸。其它组氨基酸也可通过如Creighton(1984)Proteins:Structure and Molecular Properties(2d Ed.1993),W.H.Freeman andCompany所述的原理来表示。More conservative substitution groups include: valine-leucine-isoleucine, phenylalanine-tyrosine, lysine-arginine, alanine-valine, and aspartate- glutamic acid. Other groups of amino acids can also be represented by principles such as those described by Creighton (1984) Proteins: Structure and Molecular Properties (2d Ed. 1993), W.H. Freeman and Company.
在本发明的一个技术方案中,与实施例中抗体的CDR相比较,在变异的CDR中,根据亲水/疏水性质和残基分子量/大小的保守性实质上也是保留的(例如,序列的分子量种类、亲水得分或二者保留了至少约50%、至少约60%、至少约70%、至少约75%、至少约80%、至少约85%、至少约90%、至少约95%或更多(例如65-99%))。例如,保守残基的替代也可选择性地基于根据保守基团分子量的强或弱进行的替代,这在本领域是已知的。In one technical solution of the present invention, compared with the CDR of the antibody in the examples, in the variant CDR, the conservation according to the hydrophilic/hydrophobic properties and the molecular weight/size of the residues is also substantially preserved (for example, sequence At least about 50%, at least about 60%, at least about 70%, at least about 75%, at least about 80%, at least about 85%, at least about 90%, at least about 95% of the molecular weight species, hydrophilic score, or both are retained or more (eg 65-99%)). For example, substitution of conserved residues may also optionally be based on substitution based on the strength or weakness of the molecular weight of the conserved group, as is known in the art.
选择性地,也可通过相似性得分,例如通过使用BLAST程序(例如,可通过NCBI获得BLAST 2.2.8)所确定的那样来测定相似残基的 保持能力。典型地,合适的变异体与母肽具有至少约45%,譬如至少约55%、至少约65%、至少约75%、至少约85%、至少约90%、至少约95%或更高(例如约70-99%)的相似性。Alternatively, the retention of similar residues can also be determined by a similarity score, e.g., as determined using the BLAST program (e.g., BLAST 2.2.8 available through NCBI). Typically, suitable variants have at least about 45%, such as at least about 55%, at least about 65%, at least about 75%, at least about 85%, at least about 90%, at least about 95% or higher ( eg about 70-99%) similarity.
可通过选择与上述已定义的组中具有更低保守性的替代来产生功能上的实质改变。例如,可产生在改变的区域更显著地影响肽的结构的非保守性替代,例如,α-螺旋或β-折叠;在靶位点上分子的电荷或疏水性或侧链的位阻。通常期望在多肽的性质上产生最大改变的替代是那些,1)亲水残基,例如丝氨酰或苏氨酰替换为(或被替换)疏水残基,例如亮氨酰、异亮氨酰、苯丙氨酰、缬氨酰或丙氨酰;2)半胱氨酸或脯氨酸替换为(或被替换)任何其它残基;3)具有正电侧链的残基,例如赖氨酰、精氨酰或组氨酰替换为(或被替换)负电残基,例如谷氨酰或天冬氨酰;或4)具有空间位阻侧链的残基,例如苯丙氨酸替换为(或被替换)没有侧链的残基,例如甘氨酸。因此,这些及其它非保守替代可引入到其中功能/结构需要显著改变的肽变异体中,而且这种消除了结构/功能的保守性的改变是所期望的。Substantial changes in function can be made by selecting less conservative substitutions from the above defined groups. For example, non-conservative substitutions can be made that more significantly affect the structure of the peptide in altered regions, eg, α-helices or β-sheets; the charge or hydrophobicity of the molecule or steric hindrance of side chains at the target site. The substitutions that are generally expected to produce the greatest change in the properties of the polypeptide are those, 1) a hydrophilic residue such as seryl or threonyl is replaced (or replaced) by a hydrophobic residue such as leucyl, isoleucyl , phenylalanyl, valyl, or alanyl; 2) cysteine or proline is replaced (or replaced) by any other residue; 3) residues with positively charged side chains, such as lysine acyl, arginyl or histidyl are replaced (or replaced) by negatively charged residues such as glutamyl or aspartyl; or 4) residues with sterically hindered side chains such as phenylalanine are replaced by (or to be substituted for) a residue without a side chain, such as glycine. Thus, these and other non-conservative substitutions can be introduced into peptide variants where a significant change in function/structure is desired, and such changes that eliminate the conservative nature of structure/function are desired.
产生替代变异体的简便途径是利用本领域中已知方法使用噬菌体而进行的亲和力成熟技术。为了鉴定候选的高变区域位点以进行修饰,可进行丙氨酸扫描突变方法,以鉴定对抗原结合具有显著贡献的高变区域。选择性或附加地,分析抗原-抗体复合物的晶体结构以鉴定抗原-抗体间的接触位点是有益的。这些接触的残基和临近的残基可能是替代的合适候选者。A convenient way to generate substitutional variants is affinity maturation using phage by methods known in the art. To identify candidate hypervariable region sites for modification, an alanine scanning mutagenesis approach can be performed to identify hypervariable regions that contribute significantly to antigen binding. Alternatively or additionally, it may be beneficial to analyze the crystal structure of the antigen-antibody complex to identify antigen-antibody contact sites. These contact residues and neighboring residues may be suitable candidates for substitution.
当通过高变区插入以生成变异抗体时,应该考虑已知抗体中所研究的高变区长度的典型范围。例如,对于轻链可变结构域的第一个高变区而言,可在保持实质相似性及所预期的合适大小的情况下,向母抗体VL CDR1中引入插入,根据Kabat等,同上,典型地VL CDR1具有总共约9-20(例如,约10-17)个残基。同样,典型地VL CDR2具有总共长度约5-10个残基;典型地VL CDR3有约7-20个残基长;典型地VH CDR1有约10-15个残基长;典型地VH CDR2有约15-20个残基长;典型地VH CDR3有约6-30个残基长(例如,3-25残基)。使用Kabat中所述的比对和计数方法,典型地,在VH CDR3中生成位于VH区域中的插入,而且典型地,该插入靠近结构域的C末端,譬如,在母VH CDR3的约残基97-102处(例如毗邻,或C末端邻接到,母VHCDR3序列的100号 残基)。可随机制备在其高变区有插入氨基酸残基的抗体变异体,特别地,其中母抗体针对靶抗原的起始结合亲和力可使随机产生的抗体变异体易于被筛选。例如,噬菌体展示提供了一种筛选这种随机变异体的方法。When generating variant antibodies through hypervariable region insertions, the typical range of hypervariable region lengths studied in known antibodies should be considered. For example, for the first hypervariable region of the light chain variable domain, an insertion can be introduced into the VL CDR1 of the parent antibody while maintaining substantial similarity and expected appropriate size, according to Kabat et al., supra Typically, a V L CDR1 has a total of about 9-20 (eg, about 10-17) residues. Likewise, typically VL CDR2s have a total length of about 5-10 residues; typically VL CDR3s are about 7-20 residues long; typically VH CDR1s are about 10-15 residues long; typically VH CDR2s are about 15-20 residues long; typically VH CDR3s are about 6-30 residues long (eg, 3-25 residues). Using the alignment and counting methods described in Kabat, an insertion is typically generated in a VH CDR3 that is located in the VH region, and typically this insertion is near the C-terminus of the domain, for example, at the end of the parent VH CDR3. At about residues 97-102 (eg, adjacent to, or C-terminally adjacent to, residue 100 of the parent VH CDR3 sequence). Antibody variants having inserted amino acid residues in their hypervariable regions can be generated randomly, particularly where the initial binding affinity of the parent antibody for the target antigen allows the randomly generated antibody variants to be readily screened. For example, phage display provides a method to screen for such random variants.
在设计、构建和/或评估CDR变异体时,应注意到可改变CDR区域,使其与抗原决定簇更好结合。典型地,可通过提供互补表面,可能包括可伸出到抗原蛋白表面的指状结构或其它固定抗原决定簇的抗体决定簇结构来操作抗体CDRs。如果抗原决定簇没有紧密固定,抗体将不会发挥最大亲和力。但对于抗原决定簇而言,在抗体决定簇结构中,通常是几个关键残基来主要负责这种结合。因此,CDR序列在针对相同肽的抗体间,可在长度和组成上有显著差异。技术人员知道诸如酪氨酸残基(例如,位于VH CDR3序列中)这样的通常对于这种抗原决定簇结合具有显著贡献的特定残基典型地保留在CDR变异体中。When designing, constructing, and/or evaluating CDR variants, it should be noted that CDR regions can be altered to better bind epitopes. Typically, antibody CDRs can be manipulated by providing complementary surfaces, possibly including finger-like structures that can protrude to the surface of the antigenic protein, or other antibody determinant structures that immobilize the antigenic determinant. If the epitope is not tightly anchored, the antibody will not exert maximum affinity. But for antigenic determinants, in the antibody determinant structure, usually a few key residues are mainly responsible for this binding. Thus, CDR sequences can vary significantly in length and composition between antibodies raised against the same peptide. The skilled person knows that certain residues, such as tyrosine residues (eg, located in the VH CDR3 sequence), which normally contribute significantly to such antigenic determinant binding, are typically retained in CDR variants.
与抗原和母抗体间的氨基酸接触相比较,通过引入一个或多个增加抗原中存在的一个或多个氨基酸残基与抗体中存在的一个或多个氨基酸残基间的接触或在能量方面有利的相互作用的氨基酸残基(通过替代或插入),则CDR区域的变异体也可增加抗原与抗体变异体间的氨基酸接触。目的氨基酸相互作用可从疏水键相互作用、范德华相互作用和离子相互作用中选择。Increased or energetically favored contact between one or more amino acid residues present in the antigen and one or more amino acid residues present in the antibody by introducing one or more Variants in the CDR regions can also increase the amino acid contacts between the antigen and antibody variants. The amino acid interaction of interest can be selected from hydrophobic bond interaction, van der Waals interaction, and ionic interaction.
本领域技术人员要注意在设计和筛选含本发明抗体的CDR变异体的CD38BP时的其它原则。Those skilled in the art are aware of additional principles in designing and screening CD38BPs containing CDR variants of the antibodies of the invention.
对于作为实施例中的抗体的CDRs变异体的CDR变异体而言,特别是对抗CD38抗体或其片段中的变异CDR而言,典型地,应保留支持和/或定向CDR结构性环结构所需的残基;典型地,也不改变位于CDR结构性环约10埃(但选择性地只包括该区域具有约5平方埃或更大的水溶剂接触表面的残基)的残基或仅通过保守氨基酸残基替代进行改变;和/或典型地,氨基酸序列仅具有有限数量的插入和/或缺失(即便要),从而使CDR结构性类似环的结构可在变异体中保留(相关技术和相关原理的描述参见,例如Schiweck et al.,J MoIBiol.268(5),934-51(1997)、Morea,Biophys Chem.68(1-3),9-16(1997)、Shirai et al.,FEBS Lett.399(1-2),1-8(1996)、Shirai et al.,FEBS Lett.455(1-2),188-97(1999)、Reckzo et al.,Protein Eng.8(4),389-95(1995)and Eigenbrot et al.,J MoIBiol.229(4),969-95(1993))。也参见WO03/048185、WO 03/070747和WO 03/027246。For CDR variants that are variants of the CDRs of the antibodies of the examples, particularly variant CDRs in anti-CD38 antibodies or fragments thereof, typically the structural loop structures required to support and/or orient the CDRs should be retained. residues; typically, residues located within about 10 angstroms of the CDR structural loops (but selectively only including residues with about 5 square angstroms or greater of water-solvent contacting surface in this region) are also not altered or only by and/or typically, the amino acid sequence has only a limited number of insertions and/or deletions, if any, so that the CDRs are structurally loop-like structures retained in variants (related art and For a description of the relevant principles see, for example, Schiweck et al., J MoI Biol. 268(5), 934-51 (1997), Morea, Biophys Chem. 68(1-3), 9-16 (1997), Shirai et al. , FEBS Lett.399(1-2), 1-8(1996), Shirai et al., FEBS Lett.455(1-2), 188-97(1999), Reckzo et al., Protein Eng.8( 4), 389-95(1995) and Eigenbrot et al., J MoI Biol. 229(4), 969-95(1993)).

如上所述的含CDR序列的CD38BPs在保留至少实质部分(至少约50%、60%、70%、80%、90%、95%或更多)具有如SEQ ID No:2中的VL序列和如SEQ ID No:7中的VH序列的抗体,和/或具有如SEQ IDNo:12中的VL序列和如SEQ ID No:17中的VH序列的抗体,和/或具有如SEQ ID No:22中的VL序列和如SEQ ID No:27中的VH序列的抗体的亲和性/强度和/或特异性/选择性的情况下,可含有任何合适数目和组合的这种VL和VH CDRs,但可选择性地,在诸如人患者中的免疫原性、对抗原决定簇的亲和性、增加的半衰期等这样的其它特性上会有所差别。在某些情况下,这种CD38BP可比母抗体具有更高的亲和性、选择性和/或特异性。在一个技术方案中,在本发明的CD38BP中可存在少于1个完整系列的VL CDRs和/或VH CDRs。在一个技术方案中,存在所有的VL CDRs和VH CDRs。The above-mentioned CD38BPs containing CDR sequence have the V L sequence in SEQ ID No: 2 while retaining at least a substantial part (at least about 50%, 60%, 70%, 80%, 90%, 95% or more) And as the antibody of the VH sequence among the SEQ ID No:7, and/or have as the antibody of the VL sequence among the SEQ IDNo:12 and as the VH sequence among the SEQ ID No:17, and/or have as SEQ ID No: In the case of the affinity/strength and/or specificity/selectivity of the VL sequence among ID No:22 and the antibody such as the VH sequence among SEQ ID No:27, any suitable number and combination of these may be contained.

In certain instances, such CD38BP may have higher affinity, selectivity and/or specificity than the parent antibody. In one embodiment, there may be less than 1 complete set of V L CDRs and/or V H CDRs in the CD38BP of the present invention. In one embodiment, all VL CDRs and VH CDRs are present.

The present invention also provides CD38BPs, characterized in that they can be combined with an antibody (such as Antibody-003) having a V L sequence of SEQ ID No: 2 and a V H sequence such as SEQ ID No: 7, or an antibody having a V L sequence such as SEQ ID No: 12 An antibody (such as Antibody-005) having a VL sequence as in SEQ ID No: 17 and a VH sequence as in SEQ ID No: 17, or has a VL sequence as in SEQ ID No: 22 and a VH as in SEQ ID No: 27 Antibodies of the sequence (eg Antibody-024) compete (competitive inhibition) or cross-compete (ie, relatively partially inhibit the binding of the epitope) for binding to CD38.
例如,这种CD38BP可以是来源于抗体的Fab片段,该抗体可结合到与具有如SEQ IDNo:2中的VL序列和如SEQ ID No:7中的VH序列的抗体,和/或具有如SEQ ID No:12中的VL序列和如SEQ ID No:17中的VH序列的抗体,和/或具有如SEQ ID No:22中的VL序列和如SEQIDNo:27中的VH序列的抗体相结合的抗原决定簇相同或重叠的抗原决定簇上。这种Fab片段由于其与mAb分子相比较具有较小的尺寸,因此不能显著性地与上述抗体竞争结合到CD38时,虽然其所来源的抗体可以做到这一点。然而,这种CD38BP在靠近CD38区域的类似定位中也有作用(例如,在免疫连接物的CD38BP中的细胞毒素、放射性核苷等的定位)。所以,这种CD38BPs可用于本发明的方法中,因此也提供在本发明中。For example, such CD38BP may be a Fab fragment derived from an antibody that binds to an antibody having a V L sequence such as SEQ ID No: 2 and a V H sequence such as SEQ ID No: 7, and/or has An antibody having a VL sequence as in SEQ ID No: 12 and a VH sequence as in SEQ ID No: 17, and/or has a VL sequence as in SEQ ID No: 22 and a VH as in SEQ ID No: 27 Sequences of antibodies that bind to the same epitope or on overlapping epitopes. Due to its small size compared to the mAb molecule, this Fab fragment cannot significantly compete with the above-mentioned antibody for binding to CD38, although the antibody from which it is derived can do so. However, this CD38BP also plays a role in similar localization near CD38 regions (eg, localization of cytotoxins, radionucleosides, etc. in CD38BP of immunolinkers). Therefore, such CD38BPs can be used in the methods of the present invention and are therefore also provided in the present invention.
可通过任何合适的技术来测定两个或多个CD38BPs竞争结合到 CD38或CD38的一部分。在一个技术方案中,例如,竞争作用如实施例7、8和9中所述进行测定。The competition of two or more CD38BPs for binding to CD38 or a portion of CD38 can be determined by any suitable technique. In one embodiment, competition is determined as described in Examples 7, 8 and 9, for example.
本发明语境中的竞争作用是指特定分子与特定结合伴侣之间的结合倾向性在存在另一种可结合到结合伴侣的分子时有任何可检测的显著降低。典型地,竞争是指CD38BP与以下物质的结合在存在另一种CD38BP时,使用足量的两种或多种竞争性CD38BPs和CD38BPs分子通过例如ELISA分析或FACS分析(如实施例部分所述)进行测定,至少约有10%的降低,譬如至少约15、或至少约20%的降低Competition in the context of the present invention refers to any detectable significant decrease in the binding propensity of a particular molecule to a particular binding partner in the presence of another molecule which can bind to the binding partner. Typically, competition refers to the binding of a CD38BP to, in the presence of another CD38BP, the use of sufficient quantities of two or more competing CD38BPs and CD38BPs molecules by, for example, ELISA analysis or FACS analysis (as described in the Examples section) A reduction of at least about 10%, such as a reduction of at least about 15, or at least about 20%, is determined
(a)CD38形式(例如,“加工过的”、“成熟的”、“未加工的”、“没加工的”或“不成熟的”CD38);(a) CD38 form (eg, "processed", "mature", "unprocessed", "unprocessed" or "immature" CD38);
(b)游离CD38形式(例如,通过体内加工产生的CD38片段);(b) Free CD38 forms (e.g., CD38 fragments produced by in vivo processing);
(c)由诸如CD31这样的与CD38相关的另一种肽和CD38组成的异源二肽;(c) a heterologous dipeptide consisting of another peptide related to CD38, such as CD31, and CD38;
(d)CD38和诸如cAMP、NAD+和/或cADPR这样的一种或多种底物组成的复合物;(d) a complex of CD38 and one or more substrates such as cAMP, NAD+ and/or cADPR;
(e)CD38与诸如CD31这样的可溶性配体组成的二聚体化的,相关联的和/或加工过的二聚体;或(e) a dimerized, associated and/or processed dimer of CD38 with a soluble ligand such as CD31; or
(f)CD38的一部分。对于多于一种的CD38和/或CD38一部分,例如,CD38特定区域的抗体结合性质在其片段中仍有保留,竞争也存在于CD38BPs间,在这种情况下,位于多个检测片段上的完全呈递的线性抗原决定簇或构象抗原决定簇,与在CD38中一样,呈递在足够大的CD38片段上。(f) A portion of CD38. For more than one type of CD38 and/or part of CD38, for example, the antibody binding properties of a specific region of CD38 are retained in its fragments, competition also exists between CD38BPs, in this case, located on multiple detection fragments Fully presented linear epitopes or conformational epitopes, as in CD38, are presented on sufficiently large fragments of CD38.
典型地,检测竞争性涉及使用第一个量的第一分子;第二个量的第二分子和第三个量的第三分子(或通过结合研究测定的标准,它与以第一和第二分子作为实际同期数据的替代数据的新结合数据相比较更为合理)来评估相对抑制的结合,其中第一、第二和第三个量都是足够的,可以比较,从而给出所讨论的分子与其它存在的分子关于选择性和/特异性方面的信息。第一、第二和第三个量可根据CD38BP的性质和所讨论的潜在靶标有所不同。例如,对于ELISA检验而言,与实施例部分所述类似,需要约5-50μg(例如,约10-50μg、约20-50μg、约5-20μg、约10-20μg等)CD38BP和/或CD38靶标检验是否存在竞争。条件也应该适于结合。典型地,生理或接近生理条件(例如,温度约20-40℃, pH约7-8等)适于CD38BP:CD38结合。Typically, detection of competition involves the use of a first amount of a first molecule; a second amount of a second molecule and a third amount of a third molecule (or a standard determined by binding studies that compares with the first and second It is more reasonable to compare the new binding data of two molecules as a surrogate data for the actual contemporaneous data) to assess the relative inhibition of binding, where the first, second and third quantities are sufficient and can be compared to give the discussed Information about the selectivity and/or specificity of the molecule and other molecules present. The first, second and third amounts may vary depending on the nature of the CD38BP and the potential target in question. For example, for an ELISA assay, about 5-50 μg (e.g., about 10-50 μg, about 20-50 μg, about 5-20 μg, about 10-20 μg, etc.) of CD38BP and/or CD38 is required, similar to that described in the Examples section Target test for competition. Conditions should also be suitable for binding. Typically, physiological or near-physiological conditions (eg, temperature about 20-40° C., pH about 7-8, etc.) are suitable for CD38BP:CD38 binding.
通常,竞争是以通过ELISA和/或FACS分析测定,相对抑制显著高于约5%为特征。需要设定较高的相对抑制的门槛作为特定语境中关于竞争的适当水平的标准/测定值(例如,当竞争分析是用于选择或筛选通过阻断另一种与CD38结合的肽或分子(例如诸如CD31这样的,也称为CD31抗原的CD38天然结合伴侣、EndoCAM、GPIIA1、PECAM-1、血小板/内皮细胞黏附分子或天然存在的抗CD38抗体)的结合功能所设计的新抗体时)。因此,例如,可以设定竞争的标准,其中在认为抗体具有充分竞争性之前,可检测至少约10%的相对抑制,可检测至少约15%的相对抑制,或者可检测至少约20%的相对抑制。在其中属于竞争性抗体的抗原决定簇紧邻抗原的情况下,竞争可为高于40%的CD38结合的相对抑制(例如,至少约45%的抑制,譬如约50%的抑制、例如至少约55%的抑制、譬如约60%的抑制、例如至少约65%的抑制、譬如约70%的抑制、例如至少约75%的抑制、譬如约80%的抑制、例如至少约85%的抑制、譬如约90%的抑制、例如至少约95%的抑制或更高水平的相对抑制)。Typically, competition is characterized by relative inhibition significantly greater than about 5%, as determined by ELISA and/or FACS analysis. A higher threshold of relative inhibition needs to be set as a criterion/determination of an appropriate level of competition in a particular context (e.g. when competition assays are used to select or screen for binding to CD38 by blocking another peptide or molecule (e.g. CD38 natural binding partners such as CD31, also known as CD31 antigen, EndoCAM, GPIIA1, PECAM-1, platelet/endothelial cell adhesion molecule or naturally occurring anti-CD38 antibodies when designing new antibodies) . Thus, for example, criteria for competition can be set wherein a relative inhibition of at least about 10% is detectable, a relative inhibition of at least about 15% is detectable, or a relative inhibition of at least about 20% is detectable before the antibody is considered sufficiently competitive. inhibition. In cases where the antigenic determinant belonging to the competing antibody is in the immediate vicinity of the antigen, the competition may be a relative inhibition of CD38 binding of greater than 40% (e.g., at least about 45% inhibition, such as about 50% inhibition, such as at least about 55% inhibition). % inhibition, such as about 60% inhibition, such as at least about 65% inhibition, such as about 70% inhibition, such as at least about 75% inhibition, such as about 80% inhibition, such as at least about 85% inhibition, such as about 90% inhibition, such as at least about 95% inhibition or a higher level of relative inhibition).
竞争可被认为是某分子和两种潜在结合伴侣之间交叉反应性的另一面。在某些技术方案中,本发明的CD38BP特异地结合到CD38的一个或多个残基或者区域上,但也不与其它肽、肽区域或分子发生交叉反应,例如,本发明提供一种不与诸如BST-1(骨髓基质细胞抗原-1)和也称为CD157的Mo5这样的与CD38同源的蛋白发生交叉反应的抗CD38抗体;或者不与诸如参与多发性骨髓瘤的组织这样的正常组织中CD38发生交叉反应的抗CD38抗体。典型地,没有交叉反应性是指当使用足够量的分子在合适的检测条件下通过ELISA和/或FACS分析进行评估时,在分子间的相对竞争抑制性低于5%。Competition can be considered the flip side of cross-reactivity between a molecule and two potential binding partners. In certain technical schemes, the CD38BP of the present invention specifically binds to one or more residues or regions of CD38, but does not cross-react with other peptides, peptide regions or molecules. For example, the present invention provides a Anti-CD38 antibodies that cross-react with proteins homologous to CD38 such as BST-1 (bone marrow stromal cell antigen-1) and Mo5, also known as CD157; or that do not interact with normal tissues such as those involved in multiple myeloma Anti-CD38 antibodies that cross-react with CD38 in tissues. Typically, no cross-reactivity means a relative competitive inhibition between molecules of less than 5% when assessed by ELISA and/or FACS analysis using sufficient quantities of the molecule under appropriate detection conditions.
在一个技术方案中,本发明提供可与诸如抗体-003这样的具有如SEQ ID No:2中的VL序列和如SEQ ID No:7中的VH序列的抗体竞争结合CD38或其部分的CD38BP。In one technical solution, the present invention provides an antibody that can compete with an antibody having a V L sequence as in SEQ ID No: 2 and a V H sequence as in SEQ ID No: 7 for binding to CD38 or a portion thereof, such as Antibody-003. CD38BP.

CD38BP.
在一个技术方案中,本发明提供可与诸如抗体-024这样的具有如 SEQ ID No:22中的VL序列和如SEQ ID No:27中的VH序列的抗体竞争结合CD38或其部分的CD38BP。In one technical solution, the present invention provides an antibody that can compete for binding to CD38 or a portion thereof with an antibody having a VL sequence as in SEQ ID No: 22 and a VH sequence as in SEQ ID No: 27, such as Antibody-024. CD38BP.
如本文其它地方所述,除非特别说明或与内容明显矛盾,涉及CD38BP与CD38的结合是指在任何合适情况下的结合,例如在存在CD38结构的构象环境中;或在线性抗原决定簇环境中。显然,在这种环境的有限子集中的结合是本发明的提供的任何CD38BP的一个重要特性。As described elsewhere herein, reference to CD38BP binding to CD38 refers to binding in any suitable context, such as in a conformational environment where the CD38 structure exists; or in the context of a linear epitope, unless otherwise specified or clearly contradicted by the context. . Clearly, binding in a limited subset of this environment is an important property of any CD38BP provided by the invention.
可在例如Harlow et al.,Antibodies:A Laboratory Manual,ColdSpringHarbor Laboratory Press,Cold Spring Harbor,N.Y.,1988),Colligan etal.,eds.,Current Protocols in Immunology,Greene Publishing Assoc,andWileyInterScience N.Y.,(1992,1993),and Muller,Meth.Enzymol.92,589-601(1983))中找到其它通过竞争抑制来测定CD3 8BP特异性的方法。Available, for example, in Harlow et al., Antibodies: A Laboratory Manual, Cold Spring Harbor Laboratory Press, Cold Spring Harbor, N.Y., 1988), Colligan et al., eds., Current Protocols in Immunology, Greene Publishing Assoc, and Wiley InterScience N.Y., (1992, 1993 ), and Muller, Meth. Enzymol. 92, 589-601 (1983)) find other methods for determining CD3 8BP specificity by competitive inhibition.
人CD38含有多个不同的抗原决定簇,它们包括(1)包括在人CD38单个肽链中的肽抗原决定簇;(2)由特定链上一个或多个非连续氨基酸和/或在空间上连续,但在不同肽链上(典型地,其中链的各自氨基酸序列在人CD38多肽序列中是不连续的)的氨基酸组成的构象抗原决定簇;(3)由诸如碳水化合物基团这样的全部或部分共价连接到人CD38的分子结构所组成的翻译后抗原决定簇;或(4)(1)-(3)的组合。Human CD38 contains a plurality of different epitopes, which include (1) peptide epitopes included in a single peptide chain of human CD38; A conformational epitope consisting of amino acids that are contiguous, but on different peptide chains (typically, the respective amino acid sequences of the chains are discontinuous in the human CD38 polypeptide sequence); (3) consist of all such as carbohydrate groups Or a post-translational epitope composed of a molecular structure partially covalently linked to human CD38; or a combination of (4)(1)-(3).
本发明中的抗原决定簇包括任何可特异结合到免疫球蛋白上的肽或肽衍生的决定簇。抗原决定簇可在任何位置(对CD38线性序列而言)、方向(对折叠的CD38或其片段而言)包含任何合适数目的氨基酸、氨基酸组合物(因此,至少部分带电)。An antigenic determinant in the present invention includes any peptide or peptide-derived determinant that specifically binds to an immunoglobulin. An antigenic determinant may comprise any suitable number, amino acid composition (thus, at least partially charged) of amino acids in any position (for CD38 linear sequence), orientation (for folded CD38 or fragments thereof).
因此,例如,抗原决定簇可在CD38一级序列的一个或多个连续或不连续位置上含有约3-10个氨基酸,典型地为3-8个氨基酸(例如,抗原决定簇可实质上由分布在CD38中1、2、3、4或5个非连续位置上的2、3、4、5、6、7或8个氨基酸残基组成)。选择性地,例如,可认为抗原决定簇被CD38上约5-40个连续的氨基酸残基的区域所限定(例如,约7-30氨基酸残基、约5-20氨基酸残基或约3-15氨基酸残基)(单独或与相邻的CD38结构域的一部分组合)。在某些抗原决定簇中,可能是只有一个氨基酸残基或仅有几个氨基酸残基对CDR或CDR(s)识别是重要的(因此,对CD38BP:CD38抗原亲和性和强度是最重要的)。 所以,可基于一个或多个这种关键残基来描述抗原决定簇,同时意识到其它残基也对抗原决定簇具有较小的贡献。在通过氨基酸区域来定义抗原决定簇的情况中,在区域中的一个或多个氨基酸对于抗体结合仅有很小的贡献,甚至没有贡献,因此这种残基可用合适的不同残基来替代,并不会导致抗原决定簇对至少某些特异针对它的CD38BPs出现“丢失”。Thus, for example, an antigenic determinant may comprise about 3-10 amino acids, typically 3-8 amino acids, at one or more consecutive or discontinuous positions in the primary sequence of CD38 (e.g., an antigenic determinant may consist essentially of 2, 3, 4, 5, 6, 7 or 8 amino acid residues distributed at 1, 2, 3, 4 or 5 non-contiguous positions in CD38). Alternatively, for example, an antigenic determinant can be considered to be defined by a region of about 5-40 contiguous amino acid residues on CD38 (e.g., about 7-30 amino acid residues, about 5-20 amino acid residues, or about 3- 15 amino acid residues) (alone or in combination with a portion of the adjacent CD38 domain). In some epitopes, it may be that only one amino acid residue or only a few amino acid residues are important for CDR or CDR(s) recognition (thus, for CD38BP: CD38 antigen affinity and strength are the most important of). Therefore, an epitope can be described based on one or more of these key residues, while recognizing that other residues also make minor contributions to the epitope. In cases where the epitope is defined by a region of amino acids, one or more amino acids in the region contribute little or even no contribution to antibody binding, so such residues may be replaced by suitable different residues, does not result in a "loss" of the epitope for at least some of the CD38BPs specific for it.
在一个技术方案中,本发明提供诸如抗CD38抗体这样的CD38BP,它可特异结合到CD38抗原决定簇上,该抗原决定簇也可以被具有如SEQ ID No:2中的VL序列和如SEQ IDNo:7中的VH序列的抗体(譬如抗体-003)、或具有如SEQ ID No:12中的VL序列和如SEQ IDNo:17中的VH序列的抗体(譬如抗体-005)、或具有如SEQ ID No:22中的VL序列和如SEQ IDNo:27中的VH序列的抗体(譬如抗体-024)特异结合。具有一个或多个不同于具有如SEQ IDNo:2中的VL序列和如SEQ ID No:7中的VH序列的抗体的CDRs、或具有如SEQ ID No:12中的VL序列和如SEQ ID No:17中的VH序列的抗体的CDRs、或具有如SEQ ID No:22中的VL序列和如SEQ ID No:27中的VH序列的抗体的CDRs的CDRs的CD38BPs可特异针对分别与作为具有如SEQ IDNo:2中的VL序列和如SEQ ID No:7中的VH序列的抗体、或具有如SEQ ID No:12中的VL序列和如SEQ ID No:17中的VH序列的抗体、或具有如SEQ ID No:22中的VL序列和如SEQ IDNo:27中的VH序列的抗体相同的抗原决定簇。在某些情况下,所述CD3 8BP可识别或比分别具有如SEQ ID No:2中的VL序列和如SEQ ID No:7中的VH序列的抗体、或具有如SEQ ID No:12中的VL序列和如SEQ ID No:17中的VH序列的抗体、或具有如SEQ ID No:22中的VL序列和如SEQ ID No:27中的VH序列的抗体更特异/选择性地针对抗原决定簇的特定结构或区域。In one technical scheme, the present invention provides CD38BP such as anti-CD38 antibody, it can specifically bind on the CD38 epitope, and this epitope can also have as SEQ ID No: V L sequence in 2 and such as SEQ ID NO: An antibody with a VH sequence in IDNo:7 (such as antibody-003), or an antibody with a VL sequence as in SEQ ID No:12 and a VH sequence as in SEQ IDNo:17 (such as antibody-005), Or an antibody (such as Antibody-024) having a VL sequence as in SEQ ID No: 22 and a VH sequence as in SEQ ID No: 27 specifically binds. Having one or more CDRs different from an antibody having a V L sequence such as SEQ ID No: 2 and a V H sequence such as SEQ ID No: 7, or having a V L sequence such as SEQ ID No: 12 and such as The CDRs of the antibody with the VH sequence in SEQ ID No: 17, or the CD38BPs having the CDRs of the CDRs of the antibody with the VL sequence in SEQ ID No: 22 and the VH sequence in SEQ ID No: 27 can be specific Respectively against the antibody having the V L sequence in SEQ ID No: 2 and the V H sequence in SEQ ID No: 7, or having the V L sequence in SEQ ID No: 12 and the antibody in SEQ ID No: 17 The antibody with the VH sequence in SEQ ID No: 22, or the antibody with the VL sequence in SEQ ID No: 22 and the VH sequence in SEQ ID No: 27 has the same epitope. In some cases, the CD3 8BP can recognize or compare with antibodies having a V L sequence as in SEQ ID No: 2 and a V H sequence as in SEQ ID No: 7, or an antibody having a sequence as in SEQ ID No: 12 The antibody with the V L sequence in and the V H sequence in SEQ ID No: 17, or the antibody with the V L sequence in SEQ ID No: 22 and the V H sequence in SEQ ID No: 27 is more specific/ Selectively target specific structures or regions of antigenic determinants.
结合了具有如SEQ ID No:2中的VL序列和如SEQ ID No:7中的VH序列的抗体(譬如抗体-003)、或具有如SEQ ID No:12中的VL序列和如SEQ ID No:17中的VH序列的抗体(譬如抗体-005)、或具有如SEQ ID No:22中的VL序列和如SEQ ID No:27中的VH序列的抗体(譬如抗体-024)的CD38抗原决定簇可通过标准图谱和描述技术来鉴定,可通过合适的技术来鉴定进一步的细节,技术人员可使用这种技术 的多种例子。通常这些技术也可用于鉴定和/或描述针对CD38BPs的抗原决定簇。对这种图谱/描述方法的实施例而言,针对抗CD38抗体的抗原决定簇可通过抗原决定簇的“足迹”对CD38蛋白中暴露的氨基/羧基进行化学修饰的方法来测定。这种足迹技术的一个具体实施例是使用HXMS(通过质谱检测的氢-氘交换),其中发生了受体和配体蛋白氨基质子的氢/氘交换、结合和回复交换,其中参与蛋白结合的骨架氨基基团在回复交换中受到保护,因此仍为含氘的。在该处通过肽裂解、快速混合高效液相色谱分离和/或电喷雾电离质谱来鉴定相关区域。参见例如Ehring H,AnalyticalBiochemistry,267(2)252-259(1999)and/or Engen,J.R.and Smith,D.L.(2001)Anal.Chem.73,256A-265A。另一个合适的抗原决定簇鉴定技术的实施例是核磁共振抗原决定簇图谱(NMR),其中典型地,对游离抗原和与诸如抗体这样的抗原结合肽复合在一起的抗原的二维NMR图谱中的信号位置进行比较。典型地,抗原选择性地用同位素15N标记,这样在NMR图谱上仅有与抗原相关的信号是可见的,而结合了肽的抗原没有信号。典型地,与游离抗原的图谱相比较,来源于氨基酸并参与抗原结合肽相互作用的抗原信号在复合物的图谱有位移,参与结合的氨基酸可被鉴定出来。参见例如Ernst Schering ResFound Workshop.(44),149-67(2004)、Huang et al.,Journal of MolecularBiology 281(1),61-67(1998)and Saito and Patterson,Methods.9(3),516-24(1996)。An antibody (such as Antibody-003) having a VL sequence as in SEQ ID No: 2 and a VH sequence as in SEQ ID No: 7, or having a VL sequence as in SEQ ID No: 12 and a VH sequence as in SEQ ID No: 12 and such as An antibody with a VH sequence in SEQ ID No: 17 (such as antibody-005), or an antibody with a VL sequence in SEQ ID No: 22 and a VH sequence in SEQ ID No: 27 (such as antibody- 024) CD38 epitopes can be identified by standard mapping and delineation techniques, further details can be identified by suitable techniques, of which various examples are available to the skilled artisan. Often these techniques can also be used to identify and/or characterize epitopes directed against CD38BPs. For an example of such a mapping/characterization method, epitopes directed against anti-CD38 antibodies can be determined by chemical modification of exposed amino/carboxyl groups in the CD38 protein by the "footprint" of the epitope. A specific example of this footprinting technique is the use of HXMS (hydrogen-deuterium exchange detected by mass spectrometry), where hydrogen/deuterium exchange, binding and back-exchange of receptor and ligand protein amino protons occur, where the proteins involved in protein binding The backbone amino group is protected in the back exchange and thus remains deuterium-containing. At this point, regions of interest are identified by peptide cleavage, fast-mix HPLC separation, and/or electrospray ionization mass spectrometry. See eg Ehring H, Analytical Biochemistry, 267(2) 252-259 (1999) and/or Engen, JRand Smith, DL (2001) Anal. Chem. 73, 256A-265A. Another example of a suitable epitope identification technique is nuclear magnetic resonance epitope mapping (NMR), where typically two-dimensional NMR spectra of free antigen and antigen complexed with an antigen-binding peptide such as an antibody The position of the signal is compared. Typically, the antigen is selectively labeled with the isotope 15 N, so that only the signal associated with the antigen is visible on the NMR spectrum, while the peptide-bound antigen has no signal. Typically, the antigen signal derived from the amino acids involved in the interaction of the antigen-binding peptide is shifted in the profile of the complex compared to the profile of the free antigen, and the amino acids involved in the binding can be identified. See, eg, Ernst Schering ResFound Workshop. (44), 149-67 (2004), Huang et al., Journal of Molecular Biology 281(1), 61-67 (1998) and Saito and Patterson, Methods. 9(3), 516 -24 (1996).
也可用质谱方法进行抗原决定簇绘图/描述。参见,例如Downward,J MassSpectrom.35(4),493-503(2000)and Kiselar and Downard,Anal Chem.71.(9),1792-801(1999)。Epitope mapping/description can also be performed using mass spectrometry methods. See, eg Downward, J Mass Spectrom. 35(4), 493-503 (2000) and Kiselar and Downard, Anal Chem. 71.(9), 1792-801 (1999).
蛋白酶消化技术也可用于抗原决定簇绘图和鉴定。可通过蛋白酶消化测定抗原决定簇相关的区域/序列,例如,通过胰蛋白酶以与CD38约1∶50的比例,在37℃,pH7-8,过夜(O/N)消化,然后通过质谱(MS)分析进行肽鉴定。然后可通过比较进行胰蛋白酶消化的样品和CD38BP温育后,再进行例如胰蛋白酶消化的样品,可鉴定出在胰蛋白酶切割中被CD38BP保护的肽(从而表明结合伴侣的足迹)。其它的胰凝乳蛋白酶、胃蛋白酶等酶也可或选择性地用作同样的抗原决定簇描述方法。在这些检测中,与具有如SEQ ID No:2中的VL序列和如SEQ ID No:7中的VH序列的抗体(譬如抗体-003)、或具有如SEQ ID No:12中的 VL序列和如SEQ ID No:17中的VH序列的抗体(譬如抗体-005)、或具有如SEQ ID No:22中的VL序列和如SEQ ID No:27中的VH序列的抗体(譬如抗体-024)具有显著相同的结果的CD3 8BP可被认为是与分别具有如SEQ ID No:2中的VL序列和如SEQ ID No:7中的VH序列的抗体(譬如抗体-003)、或具有如SEQ ID No:12中的VL序列和如SEQID No:17中的VH序列的抗体(譬如抗体-005)、或具有如SEQ ID No:22中的VL序列和如SEQ ID No:27中的VH序列的抗体(譬如抗体-024)结合相同抗原决定簇的抗体。例如,参见Manca,Ann 1st Super Sanita.27(1),15-9(1991)讨论的类似技术。通过其中一个抗体是生物素化的两个抗体与CD38竞争结合而获得的抗原决定簇图谱是鉴定相关抗原决定簇区域的另一种方法。Protease digestion techniques can also be used for epitope mapping and identification. The region/sequence associated with the epitope can be determined by protease digestion, e.g., by trypsin at a ratio of approximately 1:50 to CD38, overnight (O/N) at 37°C, pH 7-8, followed by mass spectrometry (MS ) analysis for peptide identification. Peptides that are protected by CD38BP during trypsin cleavage (thus indicating the footprint of the binding partner) can then be identified by comparing trypsinized samples with CD38BP-incubated, eg trypsinized samples. Other enzymes such as chymotrypsin, pepsin, etc. can also or alternatively be used for the same epitope delineation method. In these assays, an antibody (such as antibody-003) having a V L sequence as in SEQ ID No: 2 and a V H sequence as in SEQ ID No: 7, or having a V as in SEQ ID No: 12 An antibody with a L sequence and a VH sequence as in SEQ ID No: 17 (such as Antibody-005), or an antibody with a VL sequence as in SEQ ID No: 22 and a VH sequence as in SEQ ID No: 27 (such as Antibody-024) CD3 8BP having significantly the same result can be considered as the antibody (such as antibody- 003), or have the VL sequence as in SEQ ID No: 12 and the antibody (such as antibody-005) as the VH sequence in SEQID No: 17, or have the VL sequence as in SEQ ID No: 22 and An antibody with a VH sequence as in SEQ ID No: 27 (eg Antibody-024) binds an antibody to the same epitope. See, eg, a similar technique discussed in Manca, Ann 1st Super Sanita. 27(1), 15-9 (1991). Epitope mapping by competitive binding of two antibodies to CD38, one of which is biotinylated, is another method for identifying regions of related epitopes.
通过基于PEPSCAN的酶联免疫方法来检测抗体与线状或环状CD38肽的结合是另一种鉴定相关抗原决定簇区域的方法,例如,参见Slootstra-JW et al.Mol-Divers.1,87-96(1996)。定点突变是鉴定相关抗原决定簇区域的另一种方法,参见,例如Polyak andDeans,Blood 99,3956-3962(2002)。Detection of antibody binding to linear or cyclic CD38 peptides by PEPSCAN-based ELISA is another way to identify relevant epitopic regions, see for example Slootstra-JW et al. Mol-Divers.1, 87 -96 (1996). Site-directed mutagenesis is another approach to identify regions of relevant epitopes, see eg Polyak and Deans, Blood 99, 3956-3962 (2002).
各种噬菌体展示技术也可用于鉴定抗原决定簇。参见,例如Wangand Yu,CurrDrug Targets.5(1),1-15(2004)、Burton,Immunotechnology.1(2),87-94(1995 Aug),Cortese et al.,Immunotechnology.1(2),87-94(1995)和Irving et al.,Curr OpinChem Biol.5(3),314-24(2001)。一致的抗原决定簇也可通过修改的噬菌体展示相关的技术进行鉴定(参见http://www.cs.montana.edu/~mumey/papers/jcb03.pdf)。Various phage display techniques can also be used to identify epitopes. See, for example, Wang and Yu, CurrDrug Targets. 5(1), 1-15 (2004), Burton, Immunotechnology. 1(2), 87-94 (1995 Aug), Cortese et al., Immunotechnology. 1(2), 87-94 (1995) and Irving et al., Curr Opin Chem Biol. 5(3), 314-24 (2001). Consensus epitopes can also be identified by a modified phage display-related technique (see http://www.cs.montana.edu/~mumey/papers/jcb03.pdf ).
其它可能进行抗原决定簇绘图的方法包括晶体技术、X-射线衍射技术(譬如由Poljak和其它人在1970s-1980s开发的X-射线衍射/序列研究技)、和多中心肽合成的应用。诸如序列分析和三维结构分析等基于计算机的方法也可用于鉴定抗原决定簇。例如,可通过CD38的结构和进入的单个单克隆抗体Fab片段的结构的分子建模来测定抗原决定簇。这些和其它绘图方法在Epitope Mapping A Practical Approach(Westwoodand Hay Eds.)2001 Oxford University Press中进行了讨论。Other possible methods for epitope mapping include crystallographic techniques, X-ray diffraction techniques (such as X-ray diffraction/sequencing techniques developed by Poljak and others in the 1970s-1980s), and the use of polycentric peptide synthesis. Computer-based methods such as sequence analysis and three-dimensional structure analysis can also be used to identify epitopes. For example, epitopes can be determined by molecular modeling of the structure of CD38 and the structure of incoming single monoclonal antibody Fab fragments. These and other mapping methods are discussed in Epitope Mapping A Practical Approach (Westwood and Hay Eds.) 2001 Oxford University Press.
在一个技术方案中,本发明提供实质具有一个或多个选自具有如SEQ ID No:2中的VL序列和如SEQ ID No:7中的VH序列的抗体(譬如抗体-003)、或具有如SEQ ID No:12中的VL序列和如SEQ ID No:17中的VH序列的抗体(譬如抗体-005)、或具有如SEQ ID No:22中的VL序列和如SEQ ID No:27中的VH序列的抗体(譬如抗体-024)的mAbs的相同的特异CD38结合特征的CD38BP。In one technical solution, the present invention provides essentially having one or more antibodies (such as antibody-003) selected from the group consisting of VL sequences such as SEQ ID No: 2 and VH sequences such as SEQ ID No: 7, Or have the VL sequence as in SEQ ID No: 12 and the antibody (for example antibody-005) as the VH sequence in SEQ ID No: 17, or have the VL sequence as in SEQ ID No: 22 and as SEQ ID No: CD38BP with the same specific CD38 binding characteristics as mAbs of antibodies with VH sequences in ID No: 27 (such as Antibody-024).
绘图研究已表明,几种增强针对人CD38的单克隆抗体是与CD38的C末端区域的抗原决定簇(220-296)结合的(Hoshino et al.and Ferrero etal.)。在人和猕猴CD38序列间在该区域有3个氨基酸差异:在人中的T237、Q272和S274对应于猕猴中的A238、R273和F275。-005不与猕猴组织结合(如实施例10和11所示)。人和猴CD38序列存在有限数目的氨基酸差异,例如蛋白的羧基末端部分,例如以下人和猕猴CD38序列间的3个氨基酸差异,在人CD38s中的T237、Q272和S274对应于猕猴的猴CD38中的A238、R273和F275(比较SEQ IDNo.21和SEQ ID No.22)。-005与突变的其中SEQ ID No:31的272位谷氨酰胺残基被精氨酸残基替代(Q272R)人CD38蛋白、或突变的其中SEQID No:31的274位丝氨酸残基被苯丙氨酸残基替代(S274F)(如实施例17所示)人CD38蛋白的结合程度与其和野生型人CD38的结合程度不同。特别地,与-005的结合可被S274F位置的氨基酸替代所消除。Mapping studies have shown that several monoclonal antibodies enhanced against human CD38 bind to epitopes (220-296) in the C-terminal region of CD38 (Hoshino et al. and Ferrero et al.). There are 3 amino acid differences in this region between human and macaque CD38 sequences: T237, Q272 and S274 in human correspond to A238, R273 and F275 in macaque. -005 did not bind to macaque tissue (as shown in Examples 10 and 11). There are a limited number of amino acid differences between human and monkey CD38 sequences, such as the carboxy-terminal part of the protein, for example the following 3 amino acid differences between human and macaque CD38 sequences, T237, Q272 and S274 in human CD38s correspond to monkey CD38 in macaques A238, R273 and F275 (compare SEQ ID No. 21 and SEQ ID No. 22). -005 and mutated wherein SEQ ID No: 272 glutamine residues of 31 are replaced by arginine residues (Q272R) human CD38 protein, or mutated wherein SEQ ID No: 274 serine residues of 31 are replaced by phenylpropanoids Amino acid residue substitution (S274F) (as shown in Example 17) has a different binding degree to human CD38 protein than to wild-type human CD38. In particular, binding to -005 was abrogated by an amino acid substitution at position S274F.
因此,本发明提供与人CD38(SEQ ID No:31)结合的肽,它与其中272位谷氨酰胺残基被精氨酸残基替代的、突变的人CD38(SEQ IDNo:33)的结合程度不同于与其与人CD38(SEQ ID No:31)的结合程度。Accordingly, the present invention provides peptides that bind to human CD38 (SEQ ID No: 31), which bind to mutated human CD38 (SEQ ID No: 33) in which the glutamine residue at position 272 is replaced by an arginine residue.

Various techniques for determining the binding of a peptide to another peptide are available to those skilled in the art, such as ELISA, radioimmunoassay, BIAcore or flow cytometry.
一个测定结合的方法是通过测定肽与突变蛋白的结合的EC50,然后比较所获得的数值。另一种测定结合的方法是通过检测在饱和浓度结合的数量(例如,结合信号的平台),或通过诸如BIAcore来测定动力学速率常数kon和koff。One method of determining binding is by determining the EC50 of the binding of the peptide to the mutein and then comparing the values obtained.

为了在CD38中鉴定更特异的可能的抗原决定簇区域,可使用各种预测的分析方法。在第一个分析方法中,可分析CD38的(1)高度疏水区域(使用Kyte-Doolittle方法);(2)通过原外凸区指数方法测定抗原性;(3)通过Parker方法测定抗原性;(4)通过Hopp/Woods方法测定抗原性;及(5)通过Goldman,Engleman,and Steitz方法测定亲水性。可根据具有一个或多个这些特性来选择长10-40个氨基酸的序列。该方法的原则是通用的同一性是:许多理想的B细胞抗原决定簇是长8-10个氨基酸的亲水的、表面定向的及柔性序列。In order to identify more specific regions of potential epitopes in CD38, various predictive assays can be used. In the first assay, CD38 can be analyzed for (1) highly hydrophobic regions (using the Kyte-Doolittle method); (2) antigenicity by the original convex region index method; (3) antigenicity by the Parker method; (4) Antigenicity was determined by the Hopp/Woods method; and (5) Hydrophilicity was determined by the Goldman, Engleman, and Steitz method. Sequences 10-40 amino acids in length can be selected for having one or more of these properties.

单克隆抗体是指含具有相同结构和特异性的同源抗体群的组分。典型地,单克隆抗体是从实质同源的抗体,即含除了存在微量可能的天然发生的突变外,相同的群组成的单个抗体,获得的抗体。单克隆抗体是高度特异的,每个单克隆抗体典型地针对单个抗原决定簇,相反,多克隆抗体制品典型地包括针对不同抗原决定簇的不同抗体。抗体是单克隆的并不表示需要通过任何特定的方法来产生抗体。例如。本发明的单克隆抗体可通过Kohleret al.,Nature 256,495(1975)描述的杂交方法来产生,或可通过重组DNA方法来产生。单克隆抗体也可使用,例如Clackson et al.,Nature 352,624-628(1991)和Marks et al.,J.MoI.Biol.222.581-597(1991)所述的技术,从噬菌体抗体文库中分离。Monoclonal antibody refers to a composition comprising a population of homologous antibodies having the same structure and specificity. Typically, a monoclonal antibody is one obtained from substantially homologous antibodies, ie, a single antibody comprising the same population except for the presence of minor possible naturally occurring mutations. Monoclonal antibodies are highly specific, with each monoclonal antibody typically directed against a single epitope, in contrast, polyclonal antibody preparations typically include different antibodies directed against different epitopes. The fact that an antibody is monoclonal does not necessarily mean that the antibody was produced by any particular method. E.g. The monoclonal antibodies of the present invention can be produced by the hybridization method described in Kohler et al., Nature 256, 495 (1975), or can be produced by recombinant DNA methods. Monoclonal antibodies can also be obtained from phage antibody libraries using, for example, the techniques described in Clackson et al., Nature 352, 624-628 (1991) and Marks et al., J. MoI. Biol. 222.581-597 (1991). separate.
单克隆抗体可从任何合适的来源获得。因此,例如,单克隆抗体可从用目的抗原,例如,以在表面表达抗原的细胞形式,或者编码目的抗原的核酸形式,所免疫的鼠脾B细胞所制备的杂交瘤中获得。单克隆抗体也可从来源于免疫的人或诸如鼠、狗、灵长类等非人哺乳动物中的抗体表达细胞的杂交瘤中获得。Monoclonal antibodies can be obtained from any suitable source. Thus, for example, monoclonal antibodies can be obtained from hybridomas prepared from murine splenic B cells immunized with the antigen of interest, eg, in the form of cells expressing the antigen on their surface, or in the form of nucleic acids encoding the antigen of interest. Monoclonal antibodies can also be obtained from hybridomas derived from antibody-expressing cells in immunized humans or non-human mammals such as mice, dogs, primates, and the like.
选择性地,可在其它表达系统,包括原核细胞,譬如诸如大肠杆菌这样的微生物、藻类和昆虫细胞中表达克隆的抗体基因,用于产生单链Fv抗体。另外,抗体可在诸如羊和兔奶或鸡蛋这样的转基因非人动物,或在转基因植物中进行生产。残基,例如Verma,R.,etal.,J.lmmunol.Meth.216,165-181(1998);Pollock,et al.,J.lmmunoi.Meth.231,147-157(1999);and Fischer,R.,et al.,Biol.Chem.380,825-839(1999)。Alternatively, cloned antibody genes can be expressed in other expression systems, including prokaryotic cells, such as microorganisms such as E. coli, algae and insect cells, for the production of single chain Fv antibodies. In addition, antibodies can be produced in transgenic non-human animals such as goat and rabbit milk or eggs, or in transgenic plants. residues, such as Verma, R., et al., J.lmmunol.Meth.216, 165-181 (1998); Pollock, et al., J.lmmunoi.Meth.231, 147-157 (1999); and Fischer , R., et al., Biol. Chem. 380, 825-839 (1999).

此外,本发明的人抗体或本发明来源于其它物种的抗体可使用本领域周知的工艺,通过展示类技术来生产,包括但不限定于,噬菌体展示、逆转录病毒展示、核糖体展示及其它技术,所获得的分子可用于诸如亲和力成熟这样的另外的成熟,这类技术在本领域是周知的(参见,例如Hoogenboom et al.,J.MoI.Biol.227.381(1991)(噬菌体展示),Vaughanet al.,Nature Biotech 14.309(1996)(噬菌体展示),Hanes and Plucthau,PNASUSA 94,4937-4942(1997)(核糖体展示),Parmley and Smith,Gene 73,305-318(1988)(噬菌体展示),Scott TIBS 17,241-245(1992)、Cwirla et al.,PNAS USA 87,6378-6382(1990)、Russet et al.,Nucl.AcidsResearch 21,1081-1085(1993)、Hoogenboom et al.,Immunol.Reviews130,43-68(1992)、Chiswell and McCafferty TIBTECH 10,80-84(1992)、and US 5,733,743)。如果展示技术用于产生非人抗体,则这类抗体可被人源化,例如本文其它部分所述。In addition, the human antibodies of the present invention or antibodies derived from other species of the present invention can be produced by display-type techniques using techniques well known in the art, including but not limited to, phage display, retroviral display, ribosome display, and other techniques, the resulting molecules can be used for additional maturation such as affinity maturation, such techniques are well known in the art (see, for example, Hoogenboom et al., J.MoI.Biol.227.381 (1991) (phage display), Vaughan et al., Nature Biotech 14.309 (1996) (phage display), Hanes and Plucthau, PNASUSA 94, 4937-4942 (1997) (ribosome display), Parmley and Smith, Gene 73, 305-318 (1988) (phage display ), Scott TIBS 17, 241-245 (1992), Cwirla et al., PNAS USA 87, 6378-6382 (1990), Russet et al., Nucl.

If display techniques are used to generate non-human antibodies, such antibodies can be humanized, eg, as described elsewhere herein.
通过将人抗体的恒定结构域与非人物种的可变结构域相融合的方式可产生本发明的人源化单克隆抗体。如何制备人源化单克隆抗体的实施例可在例如US 6,054,297、US5,886,152和US 5,877,293中找到。人源化抗体被设计为与人免疫球蛋白比动物来源的单克隆抗体具有更高的同源性。来自“输入”(动物的)可变结构域的非人氨基酸残基典型地被转染到人“骨架”中。实质上,人源化可按照Winter及其同事(Jones et al.,Nature 321,522-525(1986)、Riechmann et al.,Nature 332,323-327(1988)、Verhoeyen et al.,Science 239,1534-1536(1988))的方法,通过将鼠补体决定区(“CDRs”)或CDR序列替换为人抗体的相应序列的方式来进行。因此,在这种“人源化”抗体中,人可变结构域的CDR部分已被非人物种的相应部分替代。这样,人源化抗体是典型的人抗体,其中某些CDR残基和某些可能的框架残基被啮齿类抗体的相似部位所替代。用于制备人源化抗体的人重链和轻链可变结构域的选择对降低抗原性至关重要。根据所谓的“最适”方法,筛选针对已知的人可变结构域序列完整文库的啮齿类抗体可变结构域的序列。然后,与啮齿类最接近的人序列作为人源化抗体的人框架(FR)(Sims et al.,J.Immunol.,151,2296(1993)、Chothia etal.,J.MoI.Biol.196,901(1987))。另一种方法使用了来源于特定轻链或重链亚组中所有人抗体的共有序列的特定框架。相同的框架可用于几个不同的人源化抗体(Carter etal.,PNAS USA 89,4285(1992)、Presta et al.,J.Immunol.151,2623(1993))。Humanized monoclonal antibodies of the invention can be produced by fusing constant domains of human antibodies to variable domains from a non-human species. Examples of how to prepare humanized monoclonal antibodies can be found, for example, in US 6,054,297, US 5,886,152 and US 5,877,293. Humanized antibodies are designed to have higher homology to human immunoglobulins than monoclonal antibodies of animal origin. Non-human amino acid residues from an "input" (animal's) variable domain are typically transfected into a human "backbone". In essence, humanization can be performed according to Winter and colleagues (Jones et al., Nature 321, 522-525 (1986), Riechmann et al., Nature 332, 323-327 (1988), Verhoeyen et al., Science 239 , 1534-1536 (1988)) by replacing the murine complement determining regions ("CDRs") or CDR sequences with the corresponding sequences of human antibodies. Thus, in such "humanized" antibodies, portions of the CDRs of human variable domains have been replaced by corresponding portions from a non-human species. Thus, humanized antibodies are typically human antibodies in which some CDR residues and possibly some framework residues are substituted by analogous sites from rodent antibodies. The choice of human heavy and light chain variable domains used to make humanized antibodies is critical to reducing antigenicity. According to the so-called "fittest" method, the sequences of the variable domains of rodent antibodies are screened against the complete library of known human variable domain sequences. Then, the human sequence closest to the rodent was used as the human framework (FR) of the humanized antibody (Sims et al., J.Immunol., 151, 2296 (1993), Chothia et al., J.MoI.Biol.196 , 901 (1987)). Another method uses a specific framework derived from the consensus sequence of all human antibodies in a specific subgroup of light or heavy chains. The same framework can be used for several different humanized antibodies (Carter et al., PNAS USA 89, 4285 (1992), Presta et al., J. Immunol. 151, 2623 (1993)).
典型地,人源化抗体保持对抗原高亲和性及其它有利的生物学特性也很重要。为了达到这个目的,可使用母序列和人源化序列的三维模型通过分析母序列及多种与之有关的人源化产物的过程来制备人源化抗体。通常三维免疫球蛋白模型是可获得,本领域技术人员对此比较了解。已有可示例并展现所选的候选免疫球蛋白序列的可能的三维构象结构的计算机程序。考察这些展示的结构可分析特定残基在候选免疫球蛋白序列的功能中的可能作用,即,对能影响候选免疫球蛋白与其抗原结合的能力进行分析。尽管CDR残基直接并基本上影响抗原结合,但通过这种方式,可从受体选择并组合FR残基,并输入序列,这样可使所需的诸如增加对靶抗原亲和性这样的抗体特征最大化。Typically, it is also important for humanized antibodies to retain high affinity for the antigen and other favorable biological properties. To this end, humanized antibodies can be prepared by a process of analysis of the parental sequence and various humanized products related thereto, using three-dimensional models of the parental and humanized sequences. Typically three-dimensional immunoglobulin models are available and are well understood by those skilled in the art. Computer programs are available which illustrate and display probable three-dimensional conformational structures of selected candidate immunoglobulin sequences. Examination of these displayed structures allows analysis of the likely role of particular residues in the function of the candidate immunoglobulin sequence, ie, the ability to affect the ability of the candidate immunoglobulin to bind its antigen. Although the CDR residues directly and substantially affect antigen binding, in this way FR residues can be selected and combined from the receptor and imported into sequence such that desired antibodies such as increased affinity for the target antigen can be achieved. feature maximization.
可使用任何合适的技术对鼠抗体或来自其它物种的抗体使其人源化或灵长类化,多种合适的技术已是本领域周知的(参见,例如Winterand Harris Immunol Today 14,43-46(1993)and Wright et al.,Crit.Reviewsin Immunol.125-168(1992))。目的抗体可通过重组DNA技术进行加工,以用相应的人序列来替代CH1、CH2、CH3、铰链结构域和/或框架结构域(参见WO 92/02190和US 5,530,101、US 5,585,089、US5,693,761、US 5,693,792、US5,714,350和US 5,777,085)。Murine antibodies or antibodies from other species can be humanized or primatized using any suitable technique, many of which are well known in the art (see, e.g., Winter and Harris Immunol Today 14, 43-46 (1993) and Wright et al., Crit. Reviews in Immunol. 125-168 (1992)). The antibody of interest can be processed by recombinant DNA techniques to replace the CH1, CH2, CH3 , hinge and/or framework domains with corresponding human sequences (see WO 92/02190 and US 5,530,101, US 5,585,089, US 5,693,761, US 5,693,792, US 5,714,350 and US 5,777,085).
也可按照Winter及其同事的方法(Jones et al.,Nature 321,522-525(1986)、Riechmann et al.,Nature 332,323-327(1988)、Verhoeyenet al.,Science 239,1534-1536(1988)),通过将啮齿类CDRs和CDR序列替换为相应的人抗体序列的方式来对抗体进行人源化。因此,这种“人源化”抗体在某种意义上是嵌合抗体(US 4,816,567),其中实质上少于完整的人可变区结构域已被非人物种的相应序列所替代。实际上,典型地,人源化抗体是人抗体,其中某些CDR残基及某些可能的FR残基被来自啮齿类抗体中同源位点的残基所替代。Also according to the method of Winter and his colleagues (Jones et al., Nature 321, 522-525 (1986), Riechmann et al., Nature 332, 323-327 (1988), Verhoeyen et al., Science 239, 1534-1536 (1988)), humanizing antibodies by replacing rodent CDRs and CDR sequences with the corresponding human antibody sequences. Thus, such "humanized" antibodies are chimeric antibodies in the sense (US 4,816,567) in which substantially less than an intact human variable region domain has been replaced by the corresponding sequence from a non-human species. In fact, humanized antibodies are typically human antibodies in which some CDR residues and possibly some FR residues are substituted by residues from homologous sites in rodent antibodies.
此外,用于构建嵌合免疫球蛋白基因的Ig cDNA的用途在本领域是已知的(参见,例如Liu et al.,PNAS USA 84,3439(1987)and J.Immunol.139,3521(1987))。从杂交瘤或其它产生抗体的细胞中分离mRNA,用于产生cDNA:目的cDNA可通过使用特异引物的聚合酶链反应来扩增(US 4,683,195和US 4,683,202)。选择性地,制备并筛选文库,以分离目的序列。然后将编码可变区的DNA序列与人恒定区序列融合。人恒定区(及可变区)序列可在Kabat et al.,(1991)中找到,最近的相关数据可在http://www.biochem.ucl.ac.uk/~ martin/abs/Generallnfo.html获得。典型地,通过诸如补体结合或抗体依赖的细胞毒素作用活性这样的所需的效应物功能来指导同型体的选择。示例的同型体有IgG1、IgG2、IgG3和IgG4。可使用人轻链恒定区κ或λ的其中之一。然后可通过常规方法来表达嵌合的人源化抗体。Furthermore, the use of Ig cDNA for constructing chimeric immunoglobulin genes is known in the art (see, for example, Liu et al., PNAS USA 84, 3439 (1987) and J. Immunol. 139, 3521 (1987) )). Isolation of mRNA from hybridomas or other antibody-producing cells is used to generate cDNA: the cDNA of interest can be amplified by polymerase chain reaction using specific primers (US 4,683,195 and US 4,683,202). Optionally, libraries are prepared and screened to isolate sequences of interest. The DNA sequences encoding the variable regions are then fused to human constant region sequences. Human constant region (and variable region) sequences can be found in Kabat et al., (1991), and the most recent relevant data are available at http://www.biochem.ucl.ac.uk/~martin/abs/Generallnfo . html get. Isotype selection is typically guided by desired effector functions such as complement fixation or antibody-dependent cytotoxic activity. Exemplary isotypes are IgGl, IgG2, IgG3 and IgG4. One of the human light chain constant regions, kappa or lambda, can be used. The chimeric humanized antibodies can then be expressed by conventional methods.
就多聚体而言,本发明的CD38BPs可以是任何合适的形式。抗CD38抗体及抗体片段如果不是更高的多聚体形式,例如与IgM抗体相联的抗体,则至少是异源三聚体。在其它技术方案中,CD38BP可以二聚体或单体形式存在。例如,本发明的单体CD38BPs可被任何合适的技术所修饰,以形成多聚体肽组分。In terms of multimers, the CD38BPs of the invention may be in any suitable form. Anti-CD38 antibodies and antibody fragments are at least heterotrimeric, if not higher multimeric forms, such as antibodies linked to IgM antibodies. In other technical schemes, CD38BP can exist in the form of dimers or monomers. For example, monomeric CD38BPs of the invention can be modified by any suitable technique to form multimeric peptide components.
如果需要,本发明的抗CD38抗体的种类可通过已知方法进行转换。例如,最初为IgM的本发明的抗体可经类别转换为本发明的IgG抗体。此外,类别转换技术可用于将一种IgG亚类转换为另一种,例如,从IgG1转换为IgG2。因此,本发明中抗体的效应物功能可通过同型体转换改变为,例如,用于多种治疗用途的IgG1、IgG2、IgG3、IgG4、IgD、IgA、IgE或IgM抗体。The type of anti-CD38 antibody of the present invention can be switched by a known method, if necessary. For example, an antibody of the invention that is originally IgM can be class switched to an IgG antibody of the invention. In addition, class switching techniques can be used to switch one IgG subclass to another, for example, from IgG1 to IgG2. Thus, the effector functions of the antibodies of the invention can be altered by isotype switching to, for example, IgG1, IgG2, IgG3, IgG4, IgD, IgA, IgE or IgM antibodies for various therapeutic uses.

In another embodiment, the antibody of the invention is an IgG3 antibody, such as IgG3, kappa or IgG3, lambda isotype. In another embodiment, the antibody of the invention is an IgG4 antibody, such as IgG4, kappa or IgG4, lambda isotype. In another technical solution, the antibody of the invention is an IgA1 or IgA2 antibody. In another technical solution, the antibody of the invention is an IgM antibody.
可从诸如scFv噬菌体展示文库这样的重组组合抗体文库中获得抗CD38抗体,它是用来源于人淋巴细胞的mRNA制备的人VL和VH cDNAs制成的。制备和筛选这类文库的方法在本领域是已知的。已有多种商品化的试剂盒用于生成噬菌体展示文库。还有其它的用于生成并筛选抗体展示文库的方法和试剂(参见,例如US 5,223,409、WO 92/18619、WO 91/17271、WO 92/20791、WO 92/15679、WO 93/01288、WO92/01047、WO 92/09690,Fuchs etal.,Bio/Technology 9,1370-1372(1991),Hay et al.,Hum.Antibod.Hybridomas 3,81-85(1992)、Huseet al.,Science 246,1275-1281(1989),McCafferty et al.,Nature 348,552-554(1990)、Griffiths et al.,EMBO J 12,725-734(1993),Hawkinset al.,J.MoI.Biol.226.889-896(1992)、Clackson et al.,Nature 352,624-628(1991),Gram etal.,PNAS USA 89,3576-3580(1992),Garradet al.,Bio/Technology 9,1373-1377(1991),Hoogenboom et ai.,Nuc AcidRes 19,4133-4137(1991)和Barbas et al.,PNASUSA 88,7978-7982(1991))。可使用任何适当的方法来筛选合适的VL和VH核酸序列。例如,可通过WO 93/06213中所述的抗原决定簇印迹方法来筛选VL和VH核酸。可使用诸如在例如WO92/01047,McCafferty et al.,Nature 348,552-554(1990)和Griffiths et al.,EMBOJ12,725-734(1993)所述的已知合适的方法来制备和筛选诸如scFv文库这样的抗体文库(以含人CD38的肽作为抗原)。这种抗体文库和CD38BPs的其它组合(文库、基因库等)是本发明的特征,它可用于医疗用途,以提供更全面的免疫应答;在免疫原性的肽、小分子、其它抗CD38抗体(例如,通过竞争检测)等的筛选方法中;和/或在诊断方法及组分(例如,通过标准技术可制备含可与其它抗体连接的这种抗体的点阵的免疫检测芯片)中作为工具。当选择初始的人VL和VH片段后,可进行“混合及匹配”实验,其中筛选与含CD38肽结合的初始选择的VL和VH片段的不同配对,以选取所需的VL/VH配对组合。例如,肽的反应性可通过ELISA或其它合 适的抗原决定簇分析方法来确定(参见,例如Scott,J.K.and Smith,G.P.Science249,386-390(1990)、Cwirla et al.,PNAS USA 87,6378-6382(1990)、Felici et al.,J.MoI.Biol.222,301-310(1991)and Kuwabaraet al.,Nature Biotechnology 15,74-78(1997),以上文献对这些技术和原理进行讨论)。可通过抗体对抗原的亲和性和/或其从抗原解离的动力学(解离速率)来选择抗体(参见,例如Hawkins et al.,J.MoI.Biol.226,889-896(1992))。Anti-CD38 antibodies can be obtained from recombinant combinatorial antibody libraries such as scFv phage display libraries made from human VL and VH cDNAs prepared from mRNA derived from human lymphocytes. Methods for preparing and screening such libraries are known in the art. A variety of commercial kits are available for generating phage display libraries. There are other methods and reagents for generating and screening antibody display libraries (see, e.g., US 5,223,409, WO 92/18619, WO 91/17271, WO 92/20791, WO 92/15679, WO 93/01288, WO 92/ 01047, WO 92/09690, Fuchs et al., Bio/Technology 9, 1370-1372 (1991), Hay et al., Hum. Antibod. Hybridomas 3, 81-85 (1992), Huse et al., Science 246, 1275 -1281 (1989), McCafferty et al., Nature 348, 552-554 (1990), Griffiths et al., EMBO J 12, 725-734 (1993), Hawkins et al., J.MoI.Biol.226.889-896 (1992), Clackson et al., Nature 352, 624-628 (1991), Gram et al., PNAS USA 89, 3576-3580 (1992), Garrad et al., Bio/Technology 9, 1373-1377 (1991), Hoogenboom et ai., Nuc Acid Res 19, 4133-4137 (1991) and Barbas et al., PNASUSA 88, 7978-7982 (1991)). Suitable VL and VH nucleic acid sequences can be screened using any suitable method. For example, VL and VH nucleic acids can be screened by the epitope imprinting method described in WO 93/06213. Known suitable methods such as those described in, for example, WO92/01047, McCafferty et al., Nature 348, 552-554 (1990) and Griffiths et al., EMBOJ12, 725-734 (1993) can be used to prepare and screen compounds such as An antibody library (using a peptide containing human CD38 as an antigen) such as a scFv library. Such antibody libraries and other combinations of CD38BPs (libraries, gene banks, etc.) are a feature of the present invention, which can be used in medical applications to provide a more comprehensive immune response; in immunogenic peptides, small molecules, other anti-CD38 antibodies (e.g., by competition assays), etc.; and/or in diagnostic methods and components (e.g., immunoassay chips containing dotted arrays of such antibodies that can be linked to other antibodies can be prepared by standard techniques) as tool. Once the initial human VL and VH segments are selected, "mix and match" experiments can be performed in which different pairs of the initially selected VL and VH segments that bind to the CD38-containing peptide are screened to select the desired VL /V H pairing combination. For example, the reactivity of the peptides can be determined by ELISA or other suitable epitope analysis methods (see, for example, Scott, JK and Smith, GPScience 249, 386-390 (1990), Cwirla et al., PNAS USA 87, 6378-6382 (1990), Felici et al., J. MoI. Biol. 222, 301-310 (1991) and Kuwabara et al., Nature Biotechnology 15, 74-78 (1997), which discuss these techniques and principles). Antibodies can be selected by their affinity for the antigen and/or their kinetics of dissociation from the antigen (off-rate) (see, e.g., Hawkins et al., J. MoI. Biol. 226, 889-896 (1992 )).
为了进一步改善抗CD38抗体的质量和/或多样性,VL/VH对的VL 及VH片段可在例如VH和/或VL的CDR3区域中,以与天然免疫应答中负责抗体亲和力成熟的体内体细胞突变过程相似的过程进行随机突变。该体外亲和力成熟可通过用分别与VH CDR3或VL CDR3互补的PCR引物扩增VH和VL区域来实现,其中典型地引物在特定位点上“引入”四种核苷酸碱基随机混合物,这样获得的PCR产物编码在VH和/或VL CDR3区域中引入随机突变的VH和VL片段。可再次筛选与含CD38的肽结合的随机突变的VH和VL片段。In order to further improve the quality and/or diversity of anti-CD38 antibodies, the VL and VH fragments of the VL / VH pair can be located, for example, in the CDR3 region of VH and/or VL , in order to interact with those responsible for the antibody in the innate immune response. Affinity maturation is a process similar to the in vivo somatic mutation process for random mutations. This in vitro affinity maturation can be achieved by amplifying the VH and VL regions with PCR primers complementary to the VH CDR3 or VL CDR3, respectively, where typically the primers "introduce" four nucleotide bases at specific sites A random mixture, the PCR products thus obtained encode VH and VL segments with random mutations introduced in the VH and/or VL CDR3 regions. Randomly mutated VH and VL fragments can be rescreened for binding to CD38-containing peptides.
筛选后,可从展示包装体(例如,从噬菌体基因组中)中回收编码所选抗体的核酸,并通过标准重组DNA技术亚克隆到合适的载体中。如果需要,这种编码抗体的核酸可进行进一步操作,以生成其它抗体形式和CD38BPs。为了表达通过筛选组合文库分离的重组抗体,典型地,将含编码抗体序列的核酸克隆到重组表达载体中,并在适于表达核酸并产生抗体的条件下,转到合适的宿主细胞(哺乳动物细胞、酵母细胞等)内。Following selection, nucleic acid encoding the selected antibody can be recovered from the displayed package (eg, from the phage genome) and subcloned into a suitable vector by standard recombinant DNA techniques. Such antibody-encoding nucleic acids can be further manipulated to generate other antibody formats and CD38BPs, if desired. In order to express a recombinant antibody isolated by screening a combinatorial library, typically, the nucleic acid containing the sequence encoding the antibody is cloned into a recombinant expression vector, and transformed into a suitable host cell (mammalian) under conditions suitable for expressing the nucleic acid and producing the antibody. cells, yeast cells, etc.).
诸如人单链Fv(scFv)及Fab抗体片段这样的高亲和抗体肽也可使用将目标抗原固定在诸如微滴定板或珠这样的固体表面上的淘选技术从这类文库中来分离(参见,例如Barbas and Burton,Trends.Biotechnol.14,230-234(1996)and Aujame et al.,Hum.Antibodies 8,155-68(1997))。大型天然文库的噬菌体展示也使得不需免疫而直接分离人抗体成为可能(参见例如,de Haard et al.,J.Biol.Chem.274(26),18218-18230(1999))。High affinity antibody peptides such as human single chain Fv (scFv) and Fab antibody fragments can also be isolated from such libraries using panning techniques that immobilize the antigen of interest on a solid surface such as microtiter plates or beads ( See, eg, Barbas and Burton, Trends. Biotechnol. 14, 230-234 (1996) and Aujame et al., Hum. Antibodies 8, 155-68 (1997)). Phage display of large natural libraries also enables the direct isolation of human antibodies without immunization (see eg, de Haard et al., J. Biol. Chem. 274(26), 18218-18230 (1999)).
在一个技术方案中,本发明提供变异的CD38抗体。“变异的”抗CD38抗体是与母抗体(典型地,通过免疫反应来产生)在CDRs或其它VH和/或VL序列中有一个或多个氨基酸改变,及替代、缺失、插入或 添加末端序列的抗体(即使这种改变没有改善母抗体抗原决定簇结合特性,但只要保留母抗体抗原决定簇结合特性最小实质量即可)。In one technical solution, the present invention provides a variant CD38 antibody. "Variant" anti-CD38 antibodies have one or more amino acid changes, substitutions, deletions, insertions or additions in the CDRs or other VH and/or VL sequences from the parent antibody (typically, produced by immunization) Antibodies with terminal sequences (even if such alterations do not improve the epitope binding properties of the parent antibody, so long as a minimal substantial amount of the epitope binding properties of the parent antibody are retained).
在单个变异抗体中的框架区、恒定结构域和/或可变区(或其任何一个或多个CDRs)的每个中可产生抗体变异体的变异形式。选择性地,可仅在抗体框架区、可变区(或其单个CDR)、或恒定结构域中的某一个产生变异。诸如由Cunningham and Wells,Science244,1081-1085(1989)所述的这样的丙氨酸扫描突变技术可用于在生成的含变异VL、VH或替代CDR序列的CD38BPs中鉴定用于替代或缺失的合适的残基,不过也可使用其它合适的突变技术。也可使用诸如Reidhaar-Olson andSauer,Science 241,53-57(1988)or Bowie andSauer,PNAS USA 86,2152-2156(1989)所述的已知突变和筛选方法来产生并检测单个氨基酸替代。Variant forms of antibody variants can be produced in each of the framework regions, constant domains and/or variable regions (or any one or more CDRs thereof) in a single variant antibody. Alternatively, variations can be made in only one of the antibody framework regions, variable regions (or individual CDRs thereof), or constant domains. Alanine scanning mutagenesis techniques such as those described by Cunningham and Wells, Science 244, 1081-1085 (1989) can be used to identify potential for substitutions or deletions in generated CD38BPs containing variant VL , VH or alternative CDR sequences suitable residues, although other suitable mutation techniques may also be used. Single amino acid substitutions may also be generated and tested using known mutagenesis and screening methods such as those described by Reidhaar-Olson and Sauer, Science 241, 53-57 (1988) or Bowie and Sauer, PNAS USA 86, 2152-2156 (1989).
因此,例如,在抗体变异体中,可将一个或单个氨基酸残基引入或插入到,或紧邻母抗体一个或多个高变区,譬如在一个或多个CDRs中。抗CD38抗体变异体可含有任意数目的插入的氨基酸残基,只要仍保留母抗体中抗原决定簇结合特征的最少实质量即可。举例来说,本发明的抗CD38抗体变异体可含有约1-30个插入的氨基酸残基,例如约1-10个、譬如例如约2-10个、例如2-5个或譬如约1-5个插入的氨基酸残基。同样,举例来说,本发明的抗CD38抗体变异体可含有约1-30个缺失的氨基酸残基,例如约1-10个、譬如例如约2-10个、例如2-5个或譬如约1-5个缺失的氨基酸残基。同样,举例来说,本发明的抗CD38抗体变异体可含有约1-30个替代的氨基酸残基,例如约1-10个、譬如例如约2-10个、例如2-5个或譬如约1-5个替代的氨基酸残基。同样,举例来说,本发明的抗CD38抗体变异体可含有约1-30个末端序列氨基酸残基增加,例如约1-10个、譬如例如约2-10个、例如2-5个或譬如约1-5个末端序列氨基酸残基增加。本发明的抗体变异体也包含2个或多个这种插入、缺失、替代及末端序列氨基酸残基增加的组合,只要这些变异体具有母抗体相对于一个或多个CD38抗原决定簇的亲和性、特异性和/或选择性的最小实质部分即可。Thus, for example, in an antibody variant, one or single amino acid residues may be introduced or inserted into, or immediately adjacent to, one or more hypervariable regions of the parent antibody, such as in one or more CDRs. Anti-CD38 antibody variants may contain any number of inserted amino acid residues so long as a minimum substantial amount of the epitope-binding characteristics of the parent antibody is retained. For example, an anti-CD38 antibody variant of the invention may contain about 1-30 inserted amino acid residues, such as about 1-10, such as for example about 2-10, such as 2-5 or such as about 1-10 5 inserted amino acid residues. Also, for example, an anti-CD38 antibody variant of the invention may contain about 1-30 deleted amino acid residues, such as about 1-10, such as about 2-10, such as 2-5 or such as about 1-5 missing amino acid residues. Also, for example, an anti-CD38 antibody variant of the invention may contain about 1-30 substituted amino acid residues, such as about 1-10, such as about 2-10, such as 2-5 or such as about 1-5 substituted amino acid residues. Also, for example, an anti-CD38 antibody variant of the invention may contain about 1-30 terminal sequence amino acid residue additions, such as about 1-10, such as for example about 2-10, such as 2-5 or such as About 1-5 terminal sequence amino acid residues were added. The antibody variants of the present invention also comprise combinations of 2 or more such insertions, deletions, substitutions, and terminal sequence amino acid residue additions, as long as these variants have the affinity of the parent antibody for one or more CD38 epitopes A minimum substantial portion of specificity, specificity and/or selectivity is sufficient.
在本文其它地方描述了在选择抗体变异体方面的考虑(例如,氨基酸残基功能特性的保守性、基于亲水特性的氨基酸残基的保守性,和/或基于分子量/大小的氨基酸残基的保守性)。典型地,诸如保守替代变 异这样的氨基酸序列改变预计不会对母序列结构特性造成实质改变(例如,替代的氨基酸不应该破坏作为母序列功能特性的二级结构)。在例如Proteins,Structures and Molecular Principles(Creighton,Ed.,W.H.Freeman andCompany,New York(1984)),Introduction to ProteinStructure(C.Branden andJ.Tooze,eds.,Garland Publishing,New York,N.Y.(1991))and Thornton et at.,Nature 354,105(1991)中描述已知的多肽二级和三级结构的例子。其它关于设计和构建肽变异体的原则在例如Collinet et al.,J Biol Chem 2Z5(23),17428-33(2000)中有所讨论。Considerations in selecting antibody variants (e.g., conservation of functional properties of amino acid residues, conservation of amino acid residues based on hydrophilic properties, and/or conservation of amino acid residues based on molecular weight/size) are described elsewhere herein. conservative). Typically, amino acid sequence changes such as conservative substitution variations are not expected to result in substantial changes in the structural properties of the parent sequence (e.g., the substituted amino acids should not disrupt secondary structure that is a functional property of the parent sequence). In e.g. Proteins, Structures and Molecular Principles (Creighton, Ed., W.H. Freeman and Company, New York (1984)), Introduction to Protein Structure (C. Branden and J. Tooze, eds., Garland Publishing, New York, N.Y. (1991)) Examples of known polypeptide secondary and tertiary structures are described in and Thornton et at., Nature 354, 105 (1991). Other principles for designing and constructing peptide variants are discussed eg in Collinet et al., J Biol Chem 2Z5(23), 17428-33 (2000).
抗体的氨基酸序列变异体可通过向抗体编码核酸中引入合适的核苷酸改变(例如通过定点突变)或通过化学肽合成方式来获得。这种变异体包括,例如,在此处示例的抗体氨基酸序列中残基的缺失和/或插入和/或替代和/或末端序列增加。可产生缺失、插入和替代的任何组合,以获得所需的变异体,只要变异体具有母抗体抗原决定簇结合特性的最小实质部分即可。相对于母抗体的氨基酸序列的改变也可通过譬如改变糖基化位点的数目或位置来改变变异抗体相对于母抗体的翻译后加工过程。Amino acid sequence variants of antibodies can be obtained by introducing appropriate nucleotide changes into the antibody-encoding nucleic acid (eg, by site-directed mutagenesis) or by chemical peptide synthesis. Such variants include, for example, deletions and/or insertions and/or substitutions and/or terminal sequence additions of residues in the antibody amino acid sequences exemplified herein. Any combination of deletions, insertions, and substitutions may be made to obtain the desired variant, so long as the variant possesses a minimal substantial portion of the epitope-binding properties of the parent antibody. Changes in the amino acid sequence relative to the parent antibody can also alter the post-translational processing of the variant antibody relative to the parent antibody by, for example, altering the number or location of glycosylation sites.
本发明的变异抗体可包含诸如在CDRs这样的高变区的改变。含有这类CDR变异体的CD38BPs的实施例在本文其它部分有所描述,并且如上所述,这类CD38BPs可以是抗体。Variant antibodies of the invention may comprise changes in hypervariable regions, such as in the CDRs. Examples of CD38BPs containing such CDR variants are described elsewhere herein, and as noted above, such CD38BPs may be antibodies.
本发明的变异抗体可包含位于高变区之外的框架(FR)改变,例如在Fc区域,该改变可与诸如改变抗体功能或药物动力学特性这样的有利特性相关。例如,框架区或恒定结构域中的替代或其它修饰(插入、缺失、末端序列增加或其任何组合)与变异抗体相对于母抗体半衰期的增加相关,或可用于改变变异抗体相对于母抗体的免疫原性,以提供与另一个分子共价或非共价结合的位点,或改变补体结合这样的特性,例如导致Clq结合与CDC或FcγR结合与抗体依赖的细胞毒素作用(ADCC)的降低或增加。例如,可在重链恒定区的234、235、236、237、297、318、320和322位中一个或多个氨基酸残基处进行替代,从而可导致与未修饰的抗体相比较,在保持与抗原结合的同时在效应物功能上发生改变,参见US 5,624,821和US 5,648,260。进一步文献有WO00/42072,它揭示了具有改变的Fc区的抗体增加了ADCC,WO 94/29351,揭示了在CH2结构域N末端区域具有突变的抗体改变了抗体与FcRI结合的能力,从而降低了抗体与Clq结合的能力,这随后降低了抗体结合补体的能力。此外,Shields et al.,J.Biol.Chem.276,6591-6604(2001)描述了组合变异体,它可改善FcγRIII与例如T256A/S298A、S298A/E333A和S298A/E333A/K334A的结合。Variant antibodies of the invention may contain framework (FR) changes located outside of the hypervariable regions, for example in the Fc region, which changes may be associated with favorable properties such as altered antibody function or pharmacokinetic properties. For example, substitutions or other modifications (insertions, deletions, terminal sequence additions, or any combination thereof) in the framework regions or constant domains are associated with increased half-life of the variant antibody relative to the parent antibody, or can be used to alter the half-life of the variant antibody relative to the parent antibody. Immunogenicity, to provide a site for covalent or non-covalent binding to another molecule, or to alter the properties of complement fixation, such as resulting in a reduction in Clq binding and CDC or FcγR binding and antibody-dependent cytotoxicity (ADCC) or increase. For example, substitutions may be made at one or more of amino acid residues in positions 234, 235, 236, 237, 297, 318, 320, and 322 of the heavy chain constant region, which may result in an increase in retention compared to an unmodified antibody. Alteration in effector function concomitant with antigen binding, see US 5,624,821 and US 5,648,260. Further references are WO00/42072, which discloses that antibodies with altered Fc regions have increased ADCC, WO 94/29351, which discloses that antibodies with mutations in the N-terminal region of the CH2 domain alter the ability of antibodies to bind to FcRI, This reduces the ability of the antibody to bind Clq, which in turn reduces the ability of the antibody to bind complement. Furthermore, Shields et al., J. Biol. Chem. 276, 6591-6604 (2001) describe combinatorial variants that improve the binding of FcγRIII to eg T256A/S298A, S298A/E333A and S298A/E333A/K334A.
抗体的体外半衰期也可通过改变Ig恒定结构域或Ig类似的恒定结构域的拯救受体抗原决定簇来改善,从而使该分子不含有完整的CH2结构域或完整的Ig Fc区域,参见US6,121,022和US 6,194,551。可进一步通过在Fc区域引入突变,例如252位苏氨酸替代为亮氨酸、254位苏氨酸替代为丝氨酸、256位苏氨酸替代为苯丙氨酸来增加体外半衰期,参见US6,277,375。The in vitro half-life of antibodies can also be improved by altering the rescue receptor epitope of the Ig constant domain or an Ig-like constant domain so that the molecule does not contain a complete CH2 domain or a complete Ig Fc region, see US6,121,022 and US6,194,551. The in vitro half-life can be increased by introducing mutations into the Fc region, such as replacing threonine at position 252 with leucine, threonine at position 254 with serine, and threonine at position 256 with phenylalanine, see US6,277,375 .
在一个技术方案中,本发明提供变异的抗CD38抗体,其中抗体中潜在的T细胞抗原决定簇通过常规设计被降低或删除。这样,例如,在一个技术方案中,本发明提供“去免疫化的”抗CD38抗体,其中潜在的T细胞抗原决定簇被删除。去免疫化的抗CD38抗体的设计和构建可通过任何合适的已知技术来实现(参见,例如WO9852976中关于制备去免疫化抗体的方法),当将这种如本发明所述的CD38BPs(例如,抗CD38变异抗体)给药时,希望可消除或实质降低在人中的免疫原性。In one technical solution, the present invention provides a variant anti-CD38 antibody, wherein potential T cell epitopes in the antibody are reduced or deleted by conventional design. Thus, for example, in one embodiment, the invention provides "deimmunized" anti-CD38 antibodies in which potential T cell epitopes have been deleted. The design and construction of deimmunized anti-CD38 antibodies can be achieved by any suitable known technique (see, for example, WO9852976 on the method of preparing deimmunized antibodies), when such CD38BPs according to the present invention (such as , anti-CD38 variant antibody) administration, it is hoped that the immunogenicity in humans can be eliminated or substantially reduced.
其它框架突变包括可降低对蛋白酶水解的敏感性、降低对氧化的敏感性,和/或在相关变异抗体中赋予或改变其它生理化学或功能特性的序列改变。框架的氨基酸序列改变也可导致变异抗体中相对于母抗体糖基化模式发生改变。改变是指删除一个或多个母抗体中发现的碳水化合物部分,和/或增加一个或多个母抗体中不存在的糖基化位点。抗体的糖基化典型地是N连接或O连接的。N连接是指碳水化合物部分与天冬氨酸残基的侧链连接。三肽序列天冬氨酸-X-丝氨酸和天冬氨酸-X-苏氨酸是常见的碳水化合物部分与天冬氨酸侧链酶连接的识别序列,其中X是除脯氨酸外的任何氨基酸。因此,多肽中的这两种三肽序列的存在是潜在的糖基化位点。O连接糖基化是指诸如N乙酰半乳糖胺、半乳糖或木糖等糖与羟基氨基酸的连接,最常见的是丝氨酸或苏氨酸,但也可使用5-羟基脯氨酸或5-羟基赖氨酸。可通过改变氨基酸序列,使其含一个或多个上述三肽序列(对N连接糖基化位点而言)来增加抗体的糖基化位点。也可通过对原始抗体序列进行一个或多个丝氨酸或苏氨酸的增加、 或替代而进行改变(对O连接糖基化而言)。Other framework mutations include sequence changes that may reduce susceptibility to proteolysis, reduce susceptibility to oxidation, and/or confer or alter other physiochemical or functional properties in associated variant antibodies. Amino acid sequence changes in the framework can also result in altered glycosylation patterns in the variant antibody relative to the parent antibody. Alteration refers to deletion of one or more carbohydrate moieties found in the parent antibody, and/or addition of one or more glycosylation sites not present in the parent antibody. Glycosylation of antibodies is typically N-linked or O-linked. N-linked refers to the attachment of the carbohydrate moiety to the side chain of an aspartic acid residue. The tripeptide sequences aspartate-X-serine and aspartate-X-threonine are common recognition sequences for enzymatic attachment of carbohydrate moieties to aspartate side chains, where X is other than proline any amino acid. Therefore, the presence of these two tripeptide sequences in the polypeptide is a potential glycosylation site. O-linked glycosylation refers to the attachment of a sugar such as N-acetylgalactosamine, galactose, or xylose to a hydroxyamino acid, most commonly serine or threonine, but 5-hydroxyproline or 5-hydroxyproline can also be used Hydroxylysine. Glycosylation sites of an antibody may be increased by altering the amino acid sequence to contain one or more of the tripeptide sequences described above (for N-linked glycosylation sites). Alterations may also be made by the addition, or substitution, of one or more serine or threonine to the original antibody sequence (for O-linked glycosylation).
抗体也可在不加通常与和Fc 297位Asn连接的碳水化合物连接的海藻糖单位的转染瘤中表达,以增强Fc对FcγRIII的亲和性,从而导致在存在NK细胞时抗体的ADCC增强,参见Shield et al.,J.Biol.Chem.277.26733(2002)。其它基于海藻糖化来改变糖基化的方法如Kyowa的WO 00/61739中所述。另外,可改变糖基化以改变CDC。进一步的参考文献有WO99/54342和Umana et al.,Nat.Biotechnol.17,176(1999),描述了构建的CHO细胞系表达GntIII,导致具有改变的糖型和改善的ADCC活性的单克隆抗体的表达。Antibodies can also be expressed in transfectomas without the addition of trehalose units, usually linked to carbohydrates linked to Asn 297 of Fc, to enhance the affinity of Fc for FcγRIII, resulting in enhanced ADCC of antibodies in the presence of NK cells , see Shield et al., J. Biol. Chem. 277.26733 (2002). Other methods for altering glycosylation based on fucosylation are described in WO 00/61739 by Kyowa. Additionally, glycosylation can be altered to alter CDC. Further references are WO99/54342 and Umana et al., Nat. Biotechnol. 17, 176 (1999), describing the construction of CHO cell lines expressing GntIII, resulting in monoclonal antibodies with altered glycoforms and improved ADCC activity expression.
其它可能的制备新型抗CD38抗体的合适技术包括CDR步移突变、抗体链替换、“简约突变”(Balint and Larrick,Gene 137,109-118(1993)),和其它亲和力成熟技术(参见,例如Wu et al.,PNAS USA95,6037-42(1998))。抗体库克隆技术也可用于产生变异抗体(参见,例如WO 96/33279)。Other possible suitable techniques for making novel anti-CD38 antibodies include CDR step mutation, antibody chain replacement, "parsimony mutation" (Balint and Larrick, Gene 137, 109-118 (1993)), and other affinity maturation techniques (see, e.g., Wu et al., PNAS USA 95, 6037-42 (1998)). Antibody library cloning techniques can also be used to generate variant antibodies (see, eg, WO 96/33279).
有多种已知可产生CDR变异体的技术,任何合适的技术或其组合可用于本发明文中来产生实施例中的抗体CDRs的CDR变异体。这种技术的实施例包括删除非必需残基,如Studnicka et al.,ProteinEngineering 7,805-814(1994)所述(也参见Soderlind etal.,Immunotechnology.4(3-4),279-85(1999),CDR步移突变和其它人工亲和力成熟技术(参见,例如Yang et al.,Journal of Molecular Biology254(3).392-403(1995)),CDR替换技术,其中CDRs典型地从不同组的选择性地含合成的寡核苷酸的基因模板中扩增,并扩增VL、VH 的恒定区和/或CDRs,然后将各种片段混合(以单链或双链形式),并通过聚合酶链反应(PCR)组装,从而产生一组携带引入到母框架中的替换的CDR的基因产物编码的抗体片段,该基因产物是用可与插入限制性位点之外的位点退火的外侧引物扩增的,从而保证产生全长的产物,将其插入到选自的载体中,用于表达含变异CDR的蛋白。可通过变异体/模拟结构和母序列的结构的叠印,例如,通过比较NMR溶液结构来测定合适的结构。合理设计CDR序列变异体的有用方法如例如WO91/09967和WO 93/16184中所述。这些方法的其它实施例在本文其它部分提供。There are a variety of known techniques for generating CDR variants, and any suitable technique or combination thereof can be used in the context of the present invention to generate CDR variants of the antibody CDRs of the Examples. Examples of this technique include deletion of non-essential residues as described by Studnicka et al., Protein Engineering 7, 805-814 (1994) (see also Soderlind et al., Immunotechnology. 4(3-4), 279-85( 1999), CDR walking mutagenesis and other artificial affinity maturation techniques (see, for example, Yang et al., Journal of Molecular Biology 254(3).392-403 (1995)), CDR replacement techniques, where CDRs are typically selected from different groups of selectively amplify in gene templates containing synthetic oligonucleotides, and amplify the constant regions and/or CDRs of VL , VH , and then mix the various fragments (in single-stranded or double-stranded form), and Assembled by polymerase chain reaction (PCR), resulting in a set of antibody fragments encoded by the gene product carrying the substituted CDRs introduced into the parent framework in a manner that anneals to a site other than the insertion restriction site Amplified by the outer primers to ensure the production of full-length products, which are inserted into selected vectors for the expression of proteins containing variant CDRs. Overprinting of the structure of the variant/mock structure and the parent sequence, such as , suitable structures are determined by comparison of NMR solution structures. Useful methods for the rational design of CDR sequence variants are described, for example, in WO 91/09967 and WO 93/16184. Additional examples of these methods are provided elsewhere herein.
本发明也提供具有与CD38结合能力的本发明的抗体(包括变异抗 体)的片段(CD38结合片段)。因此,CD38BPs包括含小于天然抗体整个四聚体结构的类似抗体的分子。抗体片段可以是任何含有全长抗体一部分的肽,通常为抗原结合或其可变区部分(这包括例如含本发明抗体的CDRs的人源化抗体片段、其变异体,或其它可使抗原片段与本发明的抗体竞争结合CD38的其它CDRs)。在一个技术方案中,抗体片段是指主要由或仅由抗体分子的一部分组成的肽。在一个技术方案中,本发明提供至少含包括本发明的一个或多个VHCDRs的重链可变结构域,选择性地也含具有本发明的一个或多个VL CDRs的轻链可变结构域的一部分的抗体片段,其中重链可变结构域及选择性地轻链可变结构域选择性地与其它部分,例如免疫球蛋白恒定结构域融合。恒定结构域序列可加到重链和/或轻链序列中,形成具有部分长度重链和/或轻链的种类。可使用任何抗体同型体恒定区或其部分,包括IgG、IgM、IgA、IgD和IgE的恒定区来实现该目的。The present invention also provides fragments (CD38-binding fragments) of the antibodies (including variant antibodies) of the present invention that have the ability to bind to CD38. Thus, CD38BPs include antibody-like molecules that contain less than the entire tetrameric structure of native antibodies. Antibody fragments can be any peptide that contains a portion of a full-length antibody, typically an antigen-binding or variable region portion thereof (this includes, for example, humanized antibody fragments comprising the CDRs of an antibody of the invention, variants thereof, or other fragments that can render the antigen other CDRs that compete with the antibodies of the invention for binding to CD38). In one technical solution, an antibody fragment refers to a peptide consisting mainly or only of a part of an antibody molecule. In one technical solution, the present invention provides at least a heavy chain variable domain comprising one or more VH CDRs of the present invention, optionally also containing a light chain variable domain having one or more VL CDRs of the present invention. Antibody fragments that are part of the variable domains in which the variable domains of the heavy chain and optionally the variable domains of the light chain are selectively fused to other parts, such as immunoglobulin constant domains. Constant domain sequences may be added to the heavy and/or light chain sequences to form species with partial length heavy and/or light chains. The constant region of any antibody isotype, or portion thereof, including the constant regions of IgG, IgM, IgA, IgD, and IgE, may be used for this purpose.
CD38结合抗体片段的例子包括Fab、Fab′、F(ab′)2和Fv片段。本发明的抗体片段也包括含CDR等的肽。在一个技术方案中,本发明提供含具有任何此处所述的重链CDRs的第一多肽链和具有任何此处所述的轻链CDRs的第二多肽链,其中两个多肽链通过一个或多个链内二硫键共价连接。在一个技术方案中,本发明提供具有这种特征的两链抗体片段,其中抗体片段选自Fab、Fab′、Fab′-SH、Fv和/或F(ab′)2片段。可通过常规方法使抗体片段化,可使用上述针对整个抗体的相同方法来筛选片段。例如,可通过胃蛋白酶处理抗体来产生F(ab′)2片段。得到的F(ab′)2片段可通过处理除去二硫键,从而产生Fab1片段。可通过木瓜蛋白酶处理IgG抗体获得Fab片段;可通过胃蛋白酶消化IgG抗体获得Fab′片段。将Fab1通过如下所述巯基或二硫键连接可产生Fab1片段。Fab1片段是通过切割F(ab′)2的铰链区的二硫键而获得的抗体片段。可通过用还原剂,例如二硫苏糖醇处理F(ab′)2片段而获得Fab′片段。抗体片段肽也可通过在重组细胞中表达编码这种肽的核酸来产生(参见,例如Evans etah,J.Immunol.Meth.184,123-38(1995))。例如,编码F(ab′)2片段的一部分的嵌和基因可包括编码CH1结构域和H链铰链区的DNA序列,然后通过翻译终止密码子来产生这种截短的抗体片段分子。Examples of CD38 binding antibody fragments include Fab, Fab', F(ab') 2 and Fv fragments. The antibody fragments of the present invention also include peptides containing CDRs and the like. In one embodiment, the present invention provides a first polypeptide chain having any of the heavy chain CDRs described herein and a second polypeptide chain having any of the light chain CDRs described herein, wherein the two polypeptide chains are passed through One or more intrachain disulfide bonds are covalently linked. In one technical solution, the present invention provides a two-chain antibody fragment having such characteristics, wherein the antibody fragment is selected from Fab, Fab', Fab'-SH, Fv and/or F(ab') 2 fragments. Antibodies can be fragmented by conventional methods, and the fragments can be screened using the same methods described above for whole antibodies. For example, F(ab') 2 fragments can be produced by pepsinizing the antibody. The resulting F(ab') 2 fragment can be treated to remove the disulfide bond, thereby generating a Fab1 fragment. Fab fragments can be obtained by papain treatment of IgG antibodies; Fab' fragments can be obtained by pepsin digestion of IgG antibodies. Fab1 fragments can be generated by linking Fab1 via sulfhydryl or disulfide bonds as described below. The Fab1 fragment is an antibody fragment obtained by cleavage of the disulfide bond of the hinge region of F(ab') 2 . Fab' fragments can be obtained by treating F(ab') 2 fragments with a reducing agent, such as dithiothreitol. Antibody fragment peptides can also be produced by expressing nucleic acids encoding such peptides in recombinant cells (see, eg, Evans etah, J. Immunol. Meth. 184, 123-38 (1995)). For example, a chimera gene encoding a portion of an F(ab') 2 fragment may include DNA sequences encoding the CH1 domain and the H chain hinge region, followed by translational stop codons to generate such truncated antibody fragment molecules.
CD38BPs也包括单价抗体和单链抗体。单链抗体是其中重链和轻链 Fv区连接的肽。在一个技术方案中,本发明提供单链Fv(scFv),其中本发明的抗CD38抗体的Fv中的重链和轻链通过柔性的肽连接物(典型地约10、12、15或更多氨基酸残基)连接在单个肽链上。产生这种抗体的方法如例如US 4,946,778,Pluckthun in The Pharmacology ofMonoclonalAntibodies,vol.113,Rosenburg and Moore eds.Springer-Verlag,New York,pp.269-315(1994),Bird et al.,Science 242,423-426(1988)、Huston et al.,PNAS USA 85,5879-5883(1988)及McCaffertyet al.,Nature 348,552-554(1990)所述。如果只使用单个VH和VL,则单链抗体可以是单价的,如果使用2个VH和VL,则是二价的,如果使用多于两个VH和VL,则是多价的。CD38BPs also include monovalent antibodies and single chain antibodies. Single chain antibodies are peptides in which the Fv regions of the heavy and light chains are linked. In one technical solution, the present invention provides single-chain Fv (scFv), wherein the heavy chain and light chain in the Fv of the anti-CD38 antibody of the present invention are connected by a flexible peptide linker (typically about 10, 12, 15 or more amino acid residues) linked to a single peptide chain. Methods for producing such antibodies are described, for example, in US 4,946,778, Pluckthun in The Pharmacology of Monoclonal Antibodies, vol. 113, Rosenburg and Moore eds. Springer-Verlag, New York, pp. 269-315 (1994), Bird et al., Science 242, 423-426 (1988), Huston et al., PNAS USA 85, 5879-5883 (1988) and McCafferty et al., Nature 348, 552-554 (1990). ScFvs can be monovalent if only a single VH and VL is used, bivalent if 2 VH and VL are used, or polyvalent if more than two VH and VL are used price.
在本发明的一个技术方案中,CD38BP可来源于或与另一个功能分子,例如另一个肽或蛋白(例如Fab′片段)连接,从而产生与多个结合位点或靶抗原决定簇结合的双特异或多特异分子。例如,本发明的抗体可功能上与一个或多个其它结合分子,例如另一个抗体、肽或结合类似物连接(例如,通过化学偶联、基因融合、非共价连接或其它方式)。在一个技术方案中,CD38BP是本发明的抗体。In one technical solution of the present invention, CD38BP can be derived from or linked to another functional molecule, such as another peptide or protein (such as a Fab' fragment), thereby generating a double binding site or target antigenic determinant. Specific or multispecific molecules. For example, an antibody of the invention can be functionally linked (eg, by chemical conjugation, genetic fusion, non-covalent linkage or otherwise) to one or more other binding molecules, such as another antibody, peptide or binding analog. In one technical solution, CD38BP is the antibody of the present invention.
因此,本发明包括含至少一个对CD38的第一结合特异性和针对第二个靶抗原决定簇的第二结合特异性的双特异和多特异分子。在本发明的一个技术方案中,第二个靶抗原决定簇是Fc受体,例如人FcγRI(CD64)或人Fcα受体(CD89),或T细胞受体,例如CD3。在一个技术方案中,本发明提供可与表达FoγR、FcαR或FcεR的效应细胞(例如,单核细胞、巨噬细胞或分叶核细胞(PMNs))结合,并作用于表达CD38的细胞的双特异和多特异分子。这些双特异和多特异分子使表达CD38的细胞定位到效应细胞,并启动诸如表达CD38细胞的吞噬作用、抗体依赖的细胞毒素作用(ADCC)、细胞因子释放、或过氧化物阴离子的产生这样的Fc受体介导的效应细胞活性。Thus, the invention includes bispecific and multispecific molecules comprising at least a first binding specificity for CD38 and a second binding specificity for a second target epitope. In one embodiment of the invention, the second target epitope is an Fc receptor, such as human FcγRI (CD64) or human Fcα receptor (CD89), or a T cell receptor, such as CD3. In one technical solution, the present invention provides a dual-targeted drug that can bind to effector cells expressing FoγR, FcαR or FcεR (for example, monocytes, macrophages or segmented nuclear cells (PMNs)) and act on cells expressing CD38. Specific and multispecific molecules. These bispecific and multispecific molecules localize CD38-expressing cells to effector cells and initiate events such as phagocytosis of CD38-expressing cells, antibody-dependent cytotoxicity (ADCC), cytokine release, or superoxide anion production. Fc receptor-mediated effector cell activity.
本发明的双特异和多特异分子除了抗Fc结合特异性和抗CD38结合特异性之外,还可进一步包括第三种结合特异性。在一个技术方案中,第三种结合特异性是抗增强因子(EF)部分,例如,与表面蛋白结合的分子参与细胞毒素作用,因此,增加对靶细胞的免疫反应。“抗增强因子部分”可以是与给定分子结合的抗体,功能性抗体片段或配体,例如,抗原或受体,因此导致结合决定簇对Fc受体或靶细胞抗原的增强作用。 “抗增强因子部分”可结合Fc受体或靶细胞抗原。选择性地,抗增强因子部分可与不同于可结合第一和第二结合特异性的实体相结合。例如,抗增强因子部分可结合细胞毒素T细胞(例如,通过CD2、CD3、CD8、CD28、CD4、CD40、ICAM-1或针对靶细胞具有更高免疫应答的其它免疫细胞)。The bispecific and multispecific molecules of the present invention may further include a third binding specificity in addition to the anti-Fc binding specificity and anti-CD38 binding specificity. In one embodiment, the third binding specificity is an anti-enhancement factor (EF) moiety, eg, a molecule that binds to a surface protein involved in cytotoxicity, thereby increasing the immune response to target cells. An "anti-enhancer moiety" may be an antibody, a functional antibody fragment or a ligand that binds to a given molecule, eg, an antigen or a receptor, thus resulting in an enhanced effect of the binding determinant on an Fc receptor or target cell antigen. An "anti-enhancement factor portion" can bind an Fc receptor or a target cell antigen. Alternatively, the anti-enhancement factor portion can bind to an entity different from that to which the first and second binding specificities can bind. For example, anti-enhancement factor moieties can bind cytotoxic T cells (eg, via CD2, CD3, CD8, CD28, CD4, CD40, ICAM-1 or other immune cells with higher immune responses against target cells).
在一个技术方案中,本发明的双特异和多特异分子包含至少一个具有结合特异性的其它抗体,这种抗体包括例如Fab、Fab1、F(ab′)2、Fv或scFv。该其它抗体也可以是轻链或重链二聚体,或诸如Fv或Ladneret al在US 4,946,778中所述的单链构建体这样的任何最小片段。抗体还可以是如US 2003/0118592和US 2003/0133939所述的结合结构域免疫球蛋白融合蛋白。In one embodiment, the bispecific and multispecific molecules of the invention comprise at least one other antibody with binding specificity, such antibody including, for example, Fab, Fab1, F(ab') 2 , Fv or scFv. The other antibodies may also be light or heavy chain dimers, or any minimal fragment such as Fv or single chain constructs as described by Ladner et al in US 4,946,778. The antibody may also be a binding domain immunoglobulin fusion protein as described in US 2003/0118592 and US 2003/0133939.
在一个技术方案中,对Fc受体的结合特异性是由人单克隆抗体来提供的,其结合不被人免疫球蛋白G(IgG)所阻断。此处所用术语“IgG受体”是指位于染色体1上的8个γ链基因中的任何一个。这些基因共编码12个可分属于3个Fc*受体种类:FcγRI(CD64)、FcγRII(CD32)和FcγRIII(CD16)转膜或可溶性受体同型体。在一个技术方案中,Fcγ受体是人高亲和性FcγRI。Fanger等在WO 88/00052和US 4,954,617中描述了这些单克隆抗体的产生和特性。这些抗体在不同于受体的Fcγ结合位点处与FcγRI、FcγRII或FcγRIII的抗原决定簇结合,因此,它们的结合不会被生理水平的IgG完全阻断。本发明中所用的特异性抗FcγRI抗体有mAb 22、mAb 32、mAb 44、mAb 62和mAb 197。在其它技术方案中,抗Fcγ受体抗体是mAb22(H22)的人源化形式。H22抗体的产生和特性在Graziano,R.F.et al.,J.Immunol.155(10),4996-5002(1995)和WO 94/10332中有所描述。产生H22抗体的细胞系于1992年11月4曰,以HA022CL1的命名保存在美国典型培养物保藏中心,其序列号为CRL11177。In one embodiment, binding specificity for Fc receptors is provided by human monoclonal antibodies, the binding of which is not blocked by human immunoglobulin G (IgG). The term "IgG receptor" as used herein refers to any one of the eight gamma chain genes located on chromosome 1. These genes encode a total of 12 transmembrane or soluble receptor isotypes that can be classified into three Fc * receptor classes: FcγRI (CD64), FcγRII (CD32) and FcγRIII (CD16). In one embodiment, the Fcγ receptor is human high affinity FcγRI. Fanger et al. describe the production and characterization of these monoclonal antibodies in WO 88/00052 and US 4,954,617. These antibodies bind to epitopes of FcγRI, FcγRII or FcγRIII at an Fcγ-binding site distinct from the receptor and, therefore, their binding is not completely blocked by physiological levels of IgG. The specific anti-FcγRI antibodies used in the present invention are mAb 22, mAb 32, mAb 44, mAb 62 and mAb 197. In other embodiments, the anti-Fcγ receptor antibody is a humanized form of mAb22 (H22). The production and characterization of the H22 antibody is described in Graziano, RF et al., J. Immunol. 155(10), 4996-5002 (1995) and WO 94/10332. The cell line producing the H22 antibody was deposited in the American Type Culture Collection under the designation HA022CL1 on November 4, 1992, and its serial number is CRL11177.
在一个技术方案中,Fc受体的结合特异性是由与人IgA受体,例如Fcα受体(Fcα1(CD89))相结合的抗体来提供的,在一个技术方案中,其结合不会被人免疫球蛋白A(IgA)所阻断。术语“IgA受体”是指含有位于染色体19上的一个α基因(FcαRI)的基因产物。已知该基因编码几个55到110kDa选择性拼接的转膜同型体。在单核细胞/巨噬细胞、嗜曙红细胞和嗜中性粒细胞的FcαRI(CD89)是组成型表达的,但在非 效应细胞群中不是这样。FcαRI对IgA1和IgA2具有中等亲和性,当与诸如G-CSF或GM-CSF这样的细胞因子接触后亲和性会提高(Morton,H.C.et al.,Critical Reviews in Immunology 16,423-440(1996))。鉴定为A3、A59、A62和A77的、可在IgA配体结合结构域之外结合FcαRI的4种FcαRI-特异性单克隆抗体已被描述(Monteiro,R.C.et al.,J.Immunol.148,1764(1992))。In one technical solution, the binding specificity of the Fc receptor is provided by an antibody that binds to a human IgA receptor, such as the Fcα receptor (Fcα1 (CD89)), and in one technical solution, its binding is not inhibited Blocked by human immunoglobulin A (IgA). The term "IgA receptor" refers to the gene product comprising an alpha gene (FcaRI) located on chromosome 19. This gene is known to encode several alternatively spliced transmembrane isoforms of 55 to 110 kDa. FcαRI (CD89) is constitutively expressed in monocytes/macrophages, eosinophils and neutrophils, but not in non-effector cell populations. FcαRI has moderate affinity for IgA1 and IgA2, which increases when exposed to cytokines such as G-CSF or GM-CSF (Morton, H.C. et al., Critical Reviews in Immunology 16, 423-440( 1996)). Four FcαRI-specific monoclonal antibodies, identified as A3, A59, A62 and A77, that bind FcαRI outside the ligand-binding domain of IgA have been described (Monteiro, R.C. et al., J. Immunol. 148, 1764 (1992)).
FcαRI、FcγRI、FcγRII和FcγRIII,特别是FcγRII和FcγRIII是本发明中所用的触发受体的实施例,这是因为它们(1)主要在免疫效应细胞,例如单核细胞、PMNs、巨噬细胞和枝状细胞上表达;(2)以高水平表达(例如,每个细胞5,000-100,000);(3)是细胞毒素作用的介导物(例如ADCC、吞噬作用);及(4)介导增强的抗原,包括自身抗原,针对它们的抗原呈递。FcαRI, FcγRI, FcγRII, and FcγRIII, particularly FcγRII and FcγRIII, are examples of triggering receptors used in the present invention because they (1) are primarily found in immune effector cells such as monocytes, PMNs, macrophages and clamocytes. (2) expressed at high levels (e.g., 5,000-100,000 per cell); (3) are mediators of cytotoxic effects (e.g., ADCC, phagocytosis); and (4) mediate enhanced Antigens, including self-antigens, are presented against their antigen.
在一个技术方案中,本发明的CD38BP是多特异性抗CD38抗体或类似抗体的分子,其特定的实施例是包含至少一对特异针对含有至少部分CD38的抗原决定簇的VH序列和VL序列链,及另一个至少一对特异针对第二个抗原决定簇的VH和VL序列链的双特异性抗体。双特异抗体中的VH和VL序列可包含对应于抗CD38 VH和VL区、变异体VH和/或VL序列、或VH和/或VL区的合适部分的完整VH和VL序列,譬如,CDR序列和足以提供与目的抗原决定簇结合的其它序列的合适组合。In one technical solution, the CD38BP of the present invention is a multispecific anti-CD38 antibody or antibody-like molecule, a specific embodiment of which comprises at least one pair of VH sequences and VL sequences specific for an antigenic determinant containing at least part of CD38. sequence chain, and another at least one pair of bispecific antibodies specific for the VH and VL sequence chains of the second antigenic determinant. The VH and VL sequences in the diabodies may comprise complete V sequences corresponding to anti-CD38 VH and VL regions, variant VH and/or VL sequences, or suitable portions of VH and/or VL regions. A suitable combination of H and VL sequences, eg, CDR sequences and other sequences sufficient to provide binding to the antigenic determinant of interest.

Typically, the second target/second molecule is a molecule other than CD38. In one technical solution, the second molecule is a cancer antigen/tumor-associated antigen, such as carcinoembryonic antigen (CEA), prostate-specific antigen (PSA), RAGE (renal antigen), α-fetoprotein, CAMEL (on melanoma Antigens that recognize CTL), CT antigens (such as MAGE-B5, -B6, -C2, -C3, and D; Mage-12; CT10; NY-ESO-1, SSX-2, GAGE, BAGE, MAGE, and SAGE), Mucin antigens (such as MUC1, mucin CA125, etc.), ganglioside antigens, tyrosinase, gp75, C-myc, Marti, MelanA, MUM-1, MUM-2, MUM-3, HLA-B7 and Ep-CAM. In one embodiment, the second molecule is a cancer-associated integrin such as α5β3 integrin. In one embodiment, the second molecule is an angiogenic growth factor or other cancer-associated growth factor, such as vascular endothelial growth factor (VEGF), fibroblast growth factor (FGF), epidermal growth factor (EGF), epidermal growth factor receptor body (EGFR), angiogenin and its receptors, especially those associated with cancer progression (eg, one of the HER1-HER4 receptors). Other cancer progression-associated proteins described herein are also suitable second molecules. In one embodiment, the second molecule is a molecule expressed on the surface of multiple myeloma cells, such as CD138.
在一个技术方案中,本发明的双特异抗体是双功能抗体。In one technical solution, the bispecific antibody of the present invention is a bifunctional antibody.
双特异抗体也包括交联的或“异源连接物”抗体。例如,在异源连接物中的抗体可与针对生物素的亲和素和其它分子偶联。例如,已计划使用这种抗体使免疫系统细胞可针对另外的细胞(参见,例如US4,676,980)。可使用任何便利的交联方法来生成异源连接物抗体。合适的肽交联试剂和技术在本领域是周知的,例如在US 4,676,980中揭示了这类试剂和技术的实施例。Bispecific antibodies also include cross-linked or "heterolinker" antibodies. For example, antibodies in the heterolinker can be conjugated to avidin and other molecules against biotin. For example, it has been planned to use such antibodies to target immune system cells against additional cells (see eg US 4,676,980). Any convenient cross-linking method can be used to generate heterolinker antibodies. Suitable peptide crosslinking reagents and techniques are well known in the art, examples of such reagents and techniques are disclosed, for example, in US 4,676,980.
因此,尽管此处讨论的是抗体,但应理解,如果合适,抗体的细节和特征可等价用于诸如Fab片段、Fab1片段和scFv肽、类似抗体的肽(含CDR的肽)、双和多特异抗体和其它CD38BPs的抗体片段,只要本发明的CD38BP保留相应完整抗体的抗原结合特性的最小实质部分即可。在某些情况下,抗体片段可具有较低的抗原结合亲和性,但可提供能弥补亲和性上任何这种损失的其它优势特征。Thus, although antibodies are discussed herein, it is to be understood that, where appropriate, the details and characteristics of antibodies are equivalently applicable to peptides such as Fab fragments, Fab1 fragments and scFv peptides, antibody-like peptides (CDR-containing peptides), bis and Antibody fragments of multispecific antibodies and other CD38BPs as long as the CD38BPs of the invention retain a minimal substantial portion of the antigen-binding properties of the corresponding intact antibodies. In certain instances, antibody fragments may have lower antigen-binding affinity, but may offer other advantageous characteristics that compensate for any such loss in affinity.
本发明的CD38BPs,特别是抗CD38抗体可基于它们能或不能提供补体结合的能力来进行选择。存在多种能进行补体结合和CDC的抗体同型体,包括但不限定于以下:鼠IgM、鼠IgG2a、鼠IgG2b、鼠IgG3、人IgM、人IgG1和人IgG3。这些不包括,也不限定的同型体鼠人IgG2和人IgG4。同型体测定和其它改变抗体的补体结合和CDC功能特征的方法是本领域已知的。本发明的CD38BPs也包括免疫黏附素,它是指其中抗CD38抗体的一个或多个CDRs与该分子共价或非共价连接的分子。免疫黏附素可与CDR(s)整合作为更大的多肽链的一部分,可将CDR(s)与另一种多肽链共价连接,或可非共价整合到CDR(s)中。CDRs可使免疫黏附素与CD38特异连接。The CD38BPs of the invention, particularly anti-CD38 antibodies, can be selected based on their ability or inability to provide complement fixation. There are a variety of antibody isotypes capable of complement fixation and CDC, including but not limited to the following: murine IgM, murine IgG2a, murine IgG2b, murine IgG3, human IgM, human IgGl and human IgG3. These do not include, and are not limited to, the isotypes murine human IgG2 and human IgG4. Isotype determination and other methods of altering the complement fixation and CDC functional characteristics of antibodies are known in the art. CD38BPs of the present invention also include immunoadhesins, which refer to molecules in which one or more CDRs of an anti-CD38 antibody are covalently or non-covalently linked to the molecule. Immunoadhesins can be integrated with CDR(s) as part of a larger polypeptide chain, can covalently link the CDR(s) to another polypeptide chain, or can be non-covalently integrated into the CDR(s). CDRs can specifically link immunoadhesin to CD38.
本发明也提供CD38BP融合蛋白。CD38BP融合蛋白可包含任何合适的氨基酸序列或特异和/或选择性地针对至少部分包含在CD38中的至少一个结构域的序列的组合(例如,抗CD38抗体VH结构域、VL结构域或特别是其CDRs),及至少一个非同源的,典型地实质不相同的氨基酸序列(例如,与CD38特异的/选择性的序列的氨基酸同一性低于约40%、低于约35%、低于约30%、低于约25%、低于约20%),它可赋予融合蛋白那些无法单独由CD38特异/选择序列所提供的可检测的生物功能和/或特性(例如,体内半衰期的延长、荧光、更多地作用于对特定细胞类型等)。这类融合蛋白的功能序列可被柔性连接物分开。二级序列也可来源于细胞毒性或凋亡的肽。二级序列也可提供诊断特性。这类序列的实施例包括那些诸如辣根过氧化物酶这样的易于可视化的酶的序列。The invention also provides CD38BP fusion proteins. A CD38BP fusion protein may comprise any suitable amino acid sequence or combination of sequences specific and/or selective for at least one domain comprised at least in part in CD38 (e.g., an anti-CD38 antibody VH domain, VL domain or particularly its CDRs), and at least one non-homologous, typically substantially non-identical, amino acid sequence (e.g., less than about 40%, less than about 35%, less than about 35% amino acid identity to a CD38-specific/selective sequence, less than about 30%, less than about 25%, less than about 20%), it can impart detectable biological functions and/or properties (e.g., in vivo half-life) to the fusion protein that cannot be provided by CD38 specific/selection sequences alone prolongation, fluorescence, more specific cell types, etc.). The functional sequences of such fusion proteins can be separated by flexible linkers. Secondary sequences can also be derived from cytotoxic or apoptotic peptides. Secondary sequences can also provide diagnostic properties. Examples of such sequences include those of easily visualized enzymes such as horseradish peroxidase.
CD38BP融合蛋白也可通过比较比较抗原决定簇标签来描述。抗原决定簇标签序列是具有足够多残基、可提供抗原决定簇用于针对生成的抗体的氨基酸序列,但在CD38BP中,该序列很短,以至于无法实质上干扰CD38BP的活性(选择性、特异性、亲和性和/或生物活性)(与缺失抗原决定簇标签的母CD38BP相比较而言)。所需的抗原决定簇标签应充分特异,从而可使抗抗原决定簇标签抗体实质上不与其它抗原决定簇发生交叉反应。合适的标签多肽一般具有至少约6个氨基酸残基,通常为8-50个氨基酸残基(例如,约9-30残基)。抗原决定簇标签的实施例包括flu HA标签多肽及其抗体12CA5(Field et ah,MoI.Cell.Biol.8,2159-2165(1988));myc标签及其抗体8F9、3C7、6E10、G4、B7和9E10(Evan et al.,MoI.Cell.Biol.5(12),3610-3616(1985)),和单纯疱疹病毒糖蛋白D(gD)标签及其抗体(Paborsky et al.,ProteinEngineering 3(6),547-553(1990))。在特定技术方案中,抗原决定簇标签是“拯救受体结合抗原决定簇”。此处所用术语“拯救受体结合抗原决定簇”是指IgG分子中Fc区的抗原决定簇(IgG1、IgG2、IgG3、或gG4),它负责增加IgG分子在体内的血清半衰期。CD38BP fusion proteins can also be described by comparing epitope tags. An epitope tag sequence is an amino acid sequence of sufficient residues to provide an epitope for antibodies raised against, but in CD38BP, the sequence is so short that it does not substantially interfere with CD38BP activity (selectivity, specificity, affinity and/or biological activity) (compared to parent CD38BP lacking the epitope tag). The desired epitope tag should be sufficiently specific such that the anti-epitope tag antibody does not substantially cross-react with other epitopes. Suitable tag polypeptides generally have at least about 6 amino acid residues, usually 8-50 amino acid residues (eg, about 9-30 residues). Examples of epitope tags include flu HA tag polypeptide and its antibody 12CA5 (Field et ah, MoI. Cell. Biol. 8, 2159-2165 (1988)); myc tag and its antibodies 8F9, 3C7, 6E10, G4, B7 and 9E10 (Evan et al., MoI.Cell.Biol.5(12), 3610-3616(1985)), and herpes simplex virus glycoprotein D (gD) tag and its antibody (Paborsky et al., ProteinEngineering 3 (6), 547-553 (1990)). In a particular embodiment, the epitope tag is a "rescue receptor binding epitope". The term "rescue receptor binding epitope" as used herein refers to an epitope in the Fc region of an IgG molecule (IgG1, IgG2, IgG3, or IgG4) that is responsible for increasing the serum half-life of the IgG molecule in vivo.
本发明的CD38BPs也包括CD38BP衍生物。衍生物是肽,其中肽的一个或多个氨基酸残基被化学修饰(例如,被烷基化、酰化、形成酯或形成氨基)或与一个或多个异源替代物(例如,亲脂性替代,PEG基团、与合适的有机基团连接物相连接的肽侧链等)共价连。肽也可与诸如细胞毒素、化疗药物、免疫抑制剂或放射性同位素(即所谓的免疫连接物)这样的治疗基团相连接。通常,此处所述的CD38BPs可被含有任何合适数目的这种修饰氨基酸的物质所修饰,和/或与这种连接替代物相联。在本文中适用性通常是通过至少在实质上保留与非衍生的母 CD38BP所具有的CD38选择性和/或特异性的能力来确定的。含有一个或多个修饰氨基酸的优势在于,例如(a)增加多肽血清半衰期,(b)降低多肽抗原性,或(c)增加多肽保藏稳定性。例如,氨基酸可在重组生产过程中,在翻译时或翻译后被修饰(例如,在哺乳动物细胞中表达时,在N-X-S/T元件上的N连接糖基化),或通过合成方式来修饰。修饰氨基酸的非限制性实施例包括糖基化氨基酸、硫酸盐氨基酸、prenlyated(例如,法尼基化、geranylgeranylated)氨基酸、乙酰化氨基酸、酰化氨基酸、PEG化氨基酸、生物素化氨基酸、羧基化氨基酸、磷酸化氨基酸等。指导技术人员进行氨基酸修饰的参考文献遍布各种文献中。实验流程可在Walker(1998)Protein Protocols On Cd-Rom,HumanaPress,Towata,NJ中找到。修饰氨基酸可选自糖基化氨基酸、PEG化氨基酸、法尼基化氨基酸、乙酰化氨基酸、生物素化氨基酸、与脂基团连接的氨基酸及与有机衍生试剂连接的氨基酸。CD38BPs of the present invention also include CD38BP derivatives. Derivatives are peptides in which one or more amino acid residues of the peptide are chemically modified (e.g., alkylated, acylated, ester-forming, or amino-forming) or with one or more heterologous substitutes (e.g., lipophilic Alternatively, a PEG group, a peptide side chain attached to a suitable organic group linker, etc.) is covalently linked. Peptides can also be linked to therapeutic groups such as cytotoxins, chemotherapeutic drugs, immunosuppressants or radioisotopes (so-called immunoconjugates). In general, the CD38BPs described herein may be modified by substances containing any suitable number of such modified amino acids, and/or associated with such linkage surrogates. Suitability in this context is generally determined by the ability to retain at least substantially the CD38 selectivity and/or specificity possessed by the non-derived parent CD38BP. The advantage of having one or more modified amino acids is, for example, to (a) increase the serum half-life of the polypeptide, (b) reduce the antigenicity of the polypeptide, or (c) increase the storage stability of the polypeptide. For example, amino acids can be modified during recombinant production, during translation or post-translationally (eg, N-linked glycosylation on N-X-S/T elements when expressed in mammalian cells), or synthetically. Non-limiting examples of modified amino acids include glycosylated amino acids, sulfated amino acids, prenlyated (e.g., farnesylated, geranylgeranylated) amino acids, acetylated amino acids, acylated amino acids, PEGylated amino acids, biotinylated amino acids, carboxylated amino acids, phosphorylated amino acids, etc. References to guide the artisan in amino acid modifications are found throughout the various literatures. The experimental protocol can be found in Walker (1998) Protein Protocols On Cd-Rom, Humana Press, Towata, NJ. The modified amino acid may be selected from glycosylated amino acids, PEGylated amino acids, farnesylated amino acids, acetylated amino acids, biotinylated amino acids, amino acids linked to lipid groups, and amino acids linked to organic derivatizing agents.
此外,可通过与多聚体共价连接的方式对抗体进行化学修饰,以例如增加其循环半衰期。作为示例的多聚体和将其连接到肽上的方法在例如US 4,766,106、US 4、179,337、US 4,495,285和US 4,609,546中有所描述。其它示例的多聚体包括聚氧乙烯化多羟基化合物和聚乙二醇(PEG)(例如,分子量在约1,000和约40,000之间,譬如在约2000和约20,000间,例如,约3,000-12,000的PEG)。In addition, antibodies can be chemically modified by covalent attachment to multimers, eg, to increase their circulating half-life. Exemplary polymers and methods of linking them to peptides are described, for example, in US 4,766,106, US 4,179,337, US 4,495,285 and US 4,609,546. Other exemplary polymers include polyoxyethylated polyols and polyethylene glycol (PEG) (e.g., PEG having a molecular weight between about 1,000 and about 40,000, such as between about 2000 and about 20,000, e.g., about 3,000-12,000 ).
在一个技术方案中,本发明提供与第二个选自放射性核、酶、酶底物、辅因子、荧光标记、化学发光标记、肽标签或磁性颗粒的分子连接的CD38BP。在一个技术方案中,CD38BP可与一个或多个抗体片段、核酸(寡核苷酸)、核酸酶、激素、免疫调节物、螯合剂、硼化合物、光敏试剂、染料等连接。这些和其它合适的试剂可直接或间接与本发明的CD38BPs偶联。与第二种试剂间接偶联的例子是通过间隔基团偶联。这些间隔可以是不溶的或可溶的(参见,例如Diener et al.,Science 231.148(1986)),并可选择间隔从而使药物在靶位点和/或在特定条件下从CD38BP释放。可与CD38BPs偶联的治疗试剂的其它实施例包括凝集素和荧光肽。In one embodiment, the present invention provides CD38BP linked to a second molecule selected from radionuclei, enzymes, enzyme substrates, cofactors, fluorescent labels, chemiluminescent labels, peptide tags or magnetic particles. In a technical solution, CD38BP can be linked with one or more antibody fragments, nucleic acid (oligonucleotide), nuclease, hormone, immune modulator, chelating agent, boron compound, photosensitizer, dye, etc. These and other suitable reagents can be conjugated directly or indirectly to the CD38BPs of the invention. An example of indirect coupling to a second reagent is through a spacer group. These spacers can be insoluble or soluble (see, eg, Diener et al., Science 231.148 (1986)), and can be chosen so that the drug is released from the CD38BP at the target site and/or under specific conditions. Other examples of therapeutic agents that can be conjugated to CD38BPs include lectins and fluorescent peptides.
在一个技术方案中,提供了含一个或多个放射性标记的氨基酸的CD38BP衍生物。放射性标记的CD38BP可用于诊断和治疗目的(与放射性分子的偶联是另一个可能的特征)。标记多肽的非限制性例子包括 但不限定于3H、14C、15N、35S、90Y、99Tc、125I、131I和186Re。制备放射性标记的氨基酸和相关的肽衍生物的方法是本领域已知的(参见,例如Junghans etal.,in Cancer Chemotherapy and Biotherapy 655-686(2dedition,Chafner andLongo,eds.,Lippincott Raven(1996))及US 4,681,581、US 4,735,210、US 5,101,827、US5,102,990(US RE35,500)、US5,648,471和US 5,697,902。例如,放射性同位素可通过氯胺T方法偶联。In one embodiment, there is provided a CD38BP derivative comprising one or more radiolabeled amino acids. Radiolabeled CD38BP can be used for diagnostic and therapeutic purposes (conjugation to radioactive molecules is another possible feature). Non-limiting examples of labeled polypeptides include, but are not limited to, 3 H, 14 C, 15 N, 35 S, 90 Y, 99 Tc, 125 I, 131 I, and 186 Re. Methods for preparing radiolabeled amino acid and related peptide derivatives are known in the art (see, e.g., Junghans et al., in Cancer Chemotherapy and Biotherapy 655-686 (2dedition, Chafner and Longo, eds., Lippincott Raven (1996)) and US 4,681,581, US 4,735,210, US 5,101,827, US 5,102,990 (US RE35,500), US 5,648,471 and US 5,697,902. For example, radioisotopes can be coupled by the chloramine T method.
在诊断中有用的放射性核是铟放射性同位素,用于治疗的是细胞毒的钇放射性同位素。通常发射质光子的放射性同位素在诊断(放射免疫显像(RIS))方法上是有用的。俄歇电子具有很短的径长(5-10nm),需要使其内在化而产生细胞毒性(参见,例如Adelstein etal.,Nucl.Med.Biol.14,165-169(1987))。因此,偶联这种放射性同位素的肽可用于诊断方法,但仅有内在化的肽被认为可释放治疗意义上的俄歇电子。α颗粒需要与细胞紧邻(在3-4个细胞直径之内),才能作为有效的治疗试剂(Vriesendorp et al.,″Radioimmunoglobulin therapy,″in High DoseCancer Therapy Armitage et al.,(eds).(Williams & Wilkins,Baltimore,Md.1992))。俄歇电子和α反射器由于其短范围发射,所以均可认为具有高度选择性,典型地不照射邻近正常细胞。The radionuclide useful in diagnosis is the indium radioisotope and the cytotoxic yttrium radioisotope in therapy. Radioisotopes that generally emit protons are useful in diagnostic (radioimmunoimaging (RIS)) methods. Auger electrons have a very short path length (5-10 nm) and need to be internalized for cytotoxicity (see, eg, Adelstein et al., Nucl. Med. Biol. 14, 165-169 (1987)). Thus, peptides conjugated to this radioisotope are useful in diagnostic methods, but only internalized peptides are thought to release Auger electrons of therapeutic interest. Alpha particles need to be in close proximity (within 3-4 cell diameters) to cells to be effective therapeutic agents (Vriesendorp et al., "Radioimmunoglobulin therapy," in High Dose Cancer Therapy Armitage et al., (eds).(Williams & Wilkins, Baltimore, Md. 1992)). Auger electrons and alpha reflectors can both be considered highly selective due to their short-range emission, typically not illuminating adjacent normal cells.
射电金属111In和90Y分别是纯的γ-发射者和纯的β-发射者。最常用的俄歇电子发射者碘-125的半衰期约为60天,通常通过免疫偶联物在体内释放(由于去卤化)。最常用于临床的α发射者砹-211和铋-212具有相对较短的半衰期(分别为7.2h和1.0h),而且在第一次α发射后衰减为不被免疫偶联物保留的放射性同位素(Wilbur,Antibiot.Immunoconjug.Radiopharm.4,5-97(1991))。对于诊断应用而言,可使用标记铟-111或锝-99m的CD38BPs。这两种放射性同位素均在合适的能量范围(100-250keV)内释放γ射线用于成像。典型地,低于该范围的能量不足以穿透而到达外部成像设备。更高的能量水平难以校准,因此所提供的诊断图像分辨率较差。99Tc的短半衰期典型地可限制其在具有快速肿瘤吸收的免疫偶联物中的使用。Radiometal 111 In and 90 Y are pure γ-emitters and pure β-emitters, respectively. The most commonly used Auger electron emitter, iodine-125, has a half-life of approximately 60 days and is usually released in vivo by immunoconjugates (due to dehalogenation). The most commonly used alpha emitters astatine-211 and bismuth-212 have relatively short half-lives (7.2h and 1.0h, respectively) and decay to radioactivity not retained by the immunoconjugate after the first alpha emission Isotopes (Wilbur, Antibiot. Immunoconjug. Radiopharm. 4, 5-97 (1991)). For diagnostic applications, CD38BPs labeled with indium-111 or technetium-99m can be used. Both radioisotopes emit gamma rays in the appropriate energy range (100-250 keV) for imaging. Typically, energy below this range is insufficient to penetrate to external imaging equipment. Higher energy levels are difficult to calibrate and therefore provide poorer resolution diagnostic images. The short half-life of99Tc can typically limit its use in immunoconjugates with rapid tumor uptake.
在一个技术方案中,提供了偶联第一和第二放射性同位素的第一和第二CD38BPs。在另一个技术方案中,提供了具有两个放射性同位素的单个CD38BP。用两个单独的放射性同位素,例如一个用于成像,另一个用于治疗的优势是利于门诊患者的治疗。诊断所用的低量放射性不具 有辐射危险,而治疗性放射性同位素,例如纯β发射者所发射的辐射典型地将大量在靶细胞邻近被吸收。In one embodiment, first and second CD38BPs coupled to first and second radioisotopes are provided. In another embodiment, a single CD38BP with two radioisotopes is provided. The advantage of using two separate radioisotopes, eg one for imaging and the other for therapy, facilitates outpatient treatment. The low levels of radioactivity used in diagnostics pose no radiation hazard, whereas radiation emitted by therapeutic radioisotopes, such as pure beta emitters, will typically be absorbed in large quantities in the vicinity of target cells.
放射性同位素可直接或间接与CD38BP连接。例如,放射性同位素 125I、131I1、99Tc、186Re和188Re可通过氨基酸功能基团与蛋白(包括抗体)共价连接。对放射性碘而言,它通常通过酪氨酸的苯基连接。有多种方法来完成这种连接:氯胺-T(参见,例如Greenwood etal.,BiochemJ.89,114-123(1963)及lodogen(Salacinski et al.,Anal.Biochem.HZ,136-146(1981))。Tc和Re放射性同位素可通过半胱氨酸巯基基团共价连接(参见,例如Griffiths et al.,Cancer Res.51,4594-4602(1991))。但这些组分相对更适于诊断目的,因为机体通常会破坏这些共价键,从而向循环系统释放放射性同位素。Radioactive isotopes can be directly or indirectly linked to CD38BP. For example, radioactive isotopes 125 I, 131 I1, 99 Tc, 186 Re and 188 Re can be covalently linked to proteins (including antibodies) through amino acid functional groups. For radioactive iodine, it is usually attached through the phenyl group of tyrosine. There are several ways to accomplish this linkage: chloramine-T (see, for example Greenwood et al., Biochem J.89, 114-123 (1963) and lodogen (Salacinski et al., Anal. Biochem. HZ, 136-146 ( 1981)). Tc and Re radioisotopes can be covalently linked via cysteine sulfhydryl groups (see, for example, Griffiths et al., Cancer Res.51, 4594-4602 (1991)). But these components are relatively more suitable For diagnostic purposes, as the body normally breaks these covalent bonds, releasing the radioisotope into the circulatory system.
CD38BP也可被用于检测的酶,例如辣根过氧化物酶、β-半乳糖苷酶、荧光素酶、碱性磷酸酶、葡萄糖氧化酶等标记。CD38BP也可用生物素标记,从而可通过亲和素或链亲和素的结合而进行间接检测。CD38BP也可用预测的被第二种报告分子(例如,亮氨酸拉链配对序列、第二种抗体的结合位点、金属结合结构域、抗原决定簇标签等)识别的多肽抗原决定簇标记。其它的酶偶联物候选者的例子包括苹果酸脱氢酶、葡萄球菌核酸酶、delta-V-类固醇异构酶、酵母乙醇脱氢酶、α-磷酸甘油脱氢酶、磷酸丙糖异构酶、天冬氨酰酶、葡萄糖氧化酶、核糖核酸酶、尿素酶、过氧化氢酶、葡萄糖-6-磷酸脱氢酶、葡糖淀粉酶和乙酰胆碱酯酶。CD38BP can also be labeled with enzymes used for detection, such as horseradish peroxidase, β-galactosidase, luciferase, alkaline phosphatase, glucose oxidase, etc. CD38BP can also be labeled with biotin, allowing indirect detection by binding of avidin or streptavidin. CD38BP can also be labeled with a polypeptide epitope predicted to be recognized by a second reporter molecule (eg, leucine zipper pairing sequence, binding site for a second antibody, metal binding domain, epitope tag, etc.). Examples of other enzyme conjugate candidates include malate dehydrogenase, staphylococcal nuclease, delta-V-steroid isomerase, yeast alcohol dehydrogenase, alpha-glycerophosphate dehydrogenase, triose phosphate isomerase enzyme, aspartylase, glucose oxidase, ribonuclease, urease, catalase, glucose-6-phosphate dehydrogenase, glucoamylase, and acetylcholinesterase.
其它的示例的标记基团通常包括但不限定于自旋标记分子和其它具有诊断价值的标记基团。Other exemplary labeling groups generally include, but are not limited to, spin-labeled molecules and other labeling groups of diagnostic value.
在一个技术方案中,本发明提供交联的CD38BP衍生物。例如,这种CD38BP衍生物可提供两个或多个(相同类型或不同类型的,例如,可产生双特异性抗体)、其中至少一个特异/选择性针对CD38的抗体交联而产生。合适的交联物包括那些通过合适的间隔区(例如,m-马来酰亚胺苯甲酸-N-羟基琥珀酰亚胺酯)而具有两个不同的反应基团的异源双功能或同源双功能(例如,二琥珀酰亚胺基底物)物质。这种连接物可从Pierce ChemicalCompany,Rockford,III获得。In one technical solution, the present invention provides cross-linked CD38BP derivatives. For example, such CD38BP derivatives can be produced by cross-linking two or more (of the same type or different types, for example, bispecific antibodies can be produced), at least one of which is specific/selective for CD38. Suitable crosslinkers include those heterobifunctional or homobifunctional with two different reactive groups via a suitable spacer (e.g., m-maleimidebenzoic acid-N-hydroxysuccinimide ester). Source Bifunctional (eg, disuccinimide-based) substances. Such linkers are available from Pierce Chemical Company, Rockford, III.
CD38BPs也可与任何合适的化学基团,例如聚乙二醇(PEG)、甲基或乙烷基团或碳水化合物基团偶联。这些和其它合适的偶联基团可用 于改善CD38BP的生物学特性,例如,增加血清半衰期、溶解性和/或组织结合能力。CD38BPs can also be coupled to any suitable chemical group, such as polyethylene glycol (PEG), methyl or ethylene groups, or carbohydrate groups. These and other suitable coupling groups can be used to improve the biological properties of CD38BP, for example, to increase serum half-life, solubility and/or tissue binding capacity.
CD38BP衍生物可将放射性同位素、蛋白或其它试剂/基团/化合物化学偶联到(a)CD38BP的N末端侧链或C末端侧链或其亚基(例如,抗CD38抗体H链、L链、或抗其CD38特异性/选择性片段)的合适取代基或侧链,或(b)CD38BP的糖链(参见,例如AntibodyEngineeringHandbook,edited by Osamu Kanemitsu,published by Chijin Shokan(1994))。在合适情况下,也可通过在内部残基或糖偶联来产生衍生物。CD38BP derivatives can chemically couple radioisotopes, proteins or other reagents/groups/compounds to (a) N-terminal side chains or C-terminal side chains of CD38BP or subunits thereof (for example, anti-CD38 antibody H chain, L chain , or against a CD38-specific/selective fragment thereof), or (b) a sugar chain of CD38BP (see, for example, Antibody Engineering Handbook, edited by Osamu Kanemitsu, published by Chijin Shokan (1994)). Derivatives may also be produced by coupling internal residues or sugars where appropriate.
CD38BPs也可用检测试剂,例如包括荧光素、荧光素硫氰酸盐、若丹明、5-二甲胺-1-萘磺酰氯化物、镧系元素磷等在内的荧光化合物来衍生。合适的荧光标记的其它实施例包括125Eu标记、异硫氰酸盐标记、藻红蛋白标记、藻蓝蛋白标记、异藻蓝蛋白标记、邻苯二甲醛标记、荧光胺标记等。化学发光标记的实施例包括鲁米诺标记、异鲁米诺标记、芳香丫啶酯标记、咪唑标记、丫啶盐标记、草酸酯标记、荧光素标记、荧光素酶标记、发光蛋白质标记等。CD38BPs can also be derivatized with detection reagents such as fluorescent compounds including fluorescein, fluorescein thiocyanate, rhodamine, 5-dimethylamine-1-naphthalenesulfonyl chloride, lanthanide phosphorus, and the like. Other examples of suitable fluorescent labels include 125 Eu labels, isothiocyanate labels, phycoerythrin labels, phycocyanin labels, isophycocyanin labels, o-phthalaldehyde labels, fluorescamine labels, and the like. Examples of chemiluminescent labels include luminol labeling, isoluminol labeling, aromatic acridine labeling, imidazole labeling, acridinium salt labeling, oxalate labeling, fluorescein labeling, luciferase labeling, luminescent protein labeling, etc. .
在一个技术方案中,CD38BP衍生物含有偶联的核酸或核酸相关的分子。在本发明的一个方面,偶联的核酸是细胞毒核糖核酸酶。在一个技术方案中,偶联的核酸是反义核酸(例如诊断反义分子的S100A10,它也可是本发明的组合组分或联合给药方法中的单独成分-参见,例如Zhang et al.,J Biol Chem.279(3),2053-62(2004))。在一个技术方案中,偶联的核酸是抑制性RNA分子(例如siRNA分子)。在一个技术方案中,偶联的核酸是免疫激活核酸(例如,免疫激活的含CpG元件的DNA分子)。在一个技术方案中,偶联的核酸是编码肿瘤抑制基因、抗癌疫苗、抗癌细胞因子或凋亡试剂表达的表达盒。这种衍生物也可含有编码一种或多种诸如植物和细菌毒素这样的细胞毒性蛋白表达的核酸偶联物。In one embodiment, the CD38BP derivative contains a conjugated nucleic acid or nucleic acid-related molecule. In one aspect of the invention, the conjugated nucleic acid is a cytotoxic ribonuclease. In one embodiment, the conjugated nucleic acid is an antisense nucleic acid (e.g. S100A10 of a diagnostic antisense molecule, which may also be a single component of a combination or combination method of the invention - see, e.g., Zhang et al., J Biol Chem. 279(3), 2053-62(2004)). In one embodiment, the conjugated nucleic acid is an inhibitory RNA molecule (eg, an siRNA molecule). In one embodiment, the conjugated nucleic acid is an immune-activating nucleic acid (eg, an immune-activating CpG element-containing DNA molecule). In one technical solution, the conjugated nucleic acid is an expression cassette encoding the expression of a tumor suppressor gene, an anticancer vaccine, an anticancer factor or an apoptotic agent. Such derivatives may also contain nucleic acid conjugates encoding the expression of one or more cytotoxic proteins such as plant and bacterial toxins.
在一个技术方案中,CD38BP与功能性核酸分子偶联。功能性核酸分子包括反义分子、干扰核酸分子(例如,siRNA分子)、核酸适体、核酶、三螺旋分子及外源性指导序列。功能性核酸分子可作为靶分子特异活性的效应物、抑制物、调节物及刺激物,或功能性核酸分子可具有独立于任何其它分子的从头合成活性。用于设计及使用反义核酸分子的 方法和技术的代表性例子可在以下非限制性美国专利列表中找到:US5,135,917、US 5,294,533、US5,627,158、US 5,641,754、US 5,691,317、US 5,780,607、US 5,786,138、US 5,849,903、US5,856,103、US 5,919,772、US 5,955,590、US 5,990,088、US 5,994,320、US 5,998,602、US6,005,095、US 6,007,995、US 6,013,522、US 6,017,898、US 6,018,042、US 6,025,198、US6,033,910、US 6,040,296、US 6,046,004、US 6,046,319和US6,057,437。In one technical solution, CD38BP is coupled to a functional nucleic acid molecule. Functional nucleic acid molecules include antisense molecules, interfering nucleic acid molecules (eg, siRNA molecules), aptamers, ribozymes, triple helix molecules, and exogenous guide sequences. Functional nucleic acid molecules can act as effectors, inhibitors, modulators, and stimulators of the specific activity of a target molecule, or functional nucleic acid molecules can have de novo synthesis activity independent of any other molecule. Representative examples of methods and techniques for designing and using antisense nucleic acid molecules can be found in the following non-limiting list of U.S. patents: US 5,135,917; US 5,294,533; US 5,627,158; US 5,641,754; 5,786,138、US 5,849,903、US5,856,103、US 5,919,772、US 5,955,590、US 5,990,088、US 5,994,320、US 5,998,602、US6,005,095、US 6,007,995、US 6,013,522、US 6,017,898、US 6,018,042、US 6,025,198、US6,033,910、US 6,040,296、 US 6,046,004, US 6,046,319 and US 6,057,437.
在一个技术方案中,CD38BP与核酸适体偶联。核酸适体是,例如以特定方式,与靶分子相互作用的分子。典型地,核酸适体是长度为15-50个碱基的小核酸,可折叠成诸如茎-环或G-四聚体这样的确定的二级和三级结构。核酸适体可与诸如ATP(US 5,631,146)和茶碱(US5,580,737)这样的小分子及诸如逆转录酶(US 5,786,462)和凝血酶(US5,543,293)这样的大分子结合。如何生成和使用与多种不同的靶分子结合的核酸适体的代表性实施例可在以下非限制性美国专利列表中找到:US 5,476,766、US 5,503,978、US 5,631,146、US5,731,424、US5,780,228、US 5,792,613、US 5,795,721、US 5,846,713、US 5,858,660、US5,861,254、US 5,864,026、US 5,869,641、US 5,958,691、US 6,001,988、US 6,011,020、US6,013,443、US 6,020,130、US 6,028,186、US 6,030,776和US 6,051,698。In one technical solution, CD38BP is coupled to a nucleic acid aptamer. Aptamers are molecules that, for example, interact with a target molecule in a specific manner. Typically, aptamers are small nucleic acids 15-50 bases in length that fold into defined secondary and tertiary structures such as stem-loop or G-tetramer. Aptamers can bind small molecules such as ATP (US 5,631,146) and theophylline (US 5,580,737) and macromolecules such as reverse transcriptase (US 5,786,462) and thrombin (US 5,543,293). Representative examples of how to generate and use nucleic acid aptamers that bind to a variety of different target molecules can be found in the following non-limiting list of U.S. patents: US 5,476,766; US 5,503,978; US 5,631,146; US 5,731,424; US 5,792,613、US 5,795,721、US 5,846,713、US 5,858,660、US5,861,254、US 5,864,026、US 5,869,641、US 5,958,691、US 6,001,988、US 6,011,020、US6,013,443、US 6,020,130、US 6,028,186、US 6,030,776和US 6,051,698。
在一个技术方案中,本发明提供与核酶偶联的CD38BP。核酶是能催化分子内或分子间化学反应的核酸分子。因此,核酶是具有催化功能的核酸。有多种不同类型的,催化核酸酶或核酸聚合酶类型反应的核酶,这些反应基于天然系统中发现的核酶,譬如(a)锤头型核酶(例如,描述在US 5,334,711、US 5,436,330、US 5,616,466、US 5,633,133、US 5,646,020、US 5,652,094、US 5,712,384、US 5,770,715、US 5,856,463、US 5,861,288、US 5,891,683、US 5,891,684、US 5,985,621、US5,989,908、US 5,998,193、US 5,998,203、WO9858058、WO 9858057和WO 9718312中)。(b)发卡型核酶(例如,描述在US 5,631,115、US 5,646,031、US 5,683,902、US 5,712,384、US 5,856,188、US 5,866,701、US 5,869,339和US6,022,962中),及(c)四膜虫型核酶(例如,描述在US 5,595,873和US 5,652,107中)。还有很多不是在天然系统中发现的核酶,但它们可被构建,以从头催化特定反应(这类实施例在例如 US 5,580,967、US 5,688,670、US 5,807,718和US 5,910,408中描述)。典型地,核酶剪切RNA或DNA底物,更通常是剪切RNA底物。典型地,核酶通过识别并结合到靶底物上及随后的切割来剪切核酸底物。该识别过程主要是基于典型的或非典型的碱基配对相互作用。因为靶底物的识别基于靶底物的序列,所以该特性使得核酶成为核酸靶特异性剪切的非常优秀的候选者。如何生成并使用核酶以催化多种不同的反应的代表性实施例可在以下非限制性美国专利列表中找到:US 5,646,042、US5,693,535、US 5,731,295、US 5,811,300、US5,837,855、US 5,869,253、US 5,877,021、US 5,877,022、US 5,972,699、US 5,972,704、US5,989,906和US 6,017,756。In one technical solution, the present invention provides CD38BP coupled with ribozyme. Ribozymes are nucleic acid molecules that catalyze intramolecular or intermolecular chemical reactions. Thus, ribozymes are nucleic acids with catalytic function. There are several different types of ribozymes that catalyze nuclease or nucleic acid polymerase type reactions based on ribozymes found in natural systems such as (a) hammerhead ribozymes (described for example in US 5,334,711, US 5,436,330 、US 5,616,466、US 5,633,133、US 5,646,020、US 5,652,094、US 5,712,384、US 5,770,715、US 5,856,463、US 5,861,288、US 5,891,683、US 5,891,684、US 5,985,621、US5,989,908、US 5,998,193、US 5,998,203、WO9858058、WO 9858057和WO 9718312). (b) hairpin-type ribozymes (for example, described in US 5,631,115, US 5,646,031, US 5,683,902, US 5,712,384, US 5,856,188, US 5,866,701, US 5,869,339 and US 6,022,962), and (c) Tetrahymena-type ribozymes ( For example, described in US 5,595,873 and US 5,652,107). There are also many ribozymes that are not found in natural systems, but which can be engineered to catalyze specific reactions de novo (such examples are described, for example, in US 5,580,967, US 5,688,670, US 5,807,718, and US 5,910,408). Typically, ribozymes cleave RNA or DNA substrates, more usually RNA substrates. Typically, ribozymes cleave a nucleic acid substrate by recognizing and binding to a target substrate and subsequent cleavage. The recognition process is mainly based on typical or atypical base-pairing interactions. This property makes ribozymes excellent candidates for target-specific cleavage of nucleic acids because the recognition of the target substrate is based on the sequence of the target substrate. Representative examples of how to make and use ribozymes to catalyze a variety of different reactions can be found in the following non-limiting list of U.S. patents: US 5,646,042; US 5,693,535; US 5,731,295; US 5,811,300; US 5,877,021, US 5,877,022, US 5,972,699, US 5,972,704, US 5,989,906 and US 6,017,756.
在一个技术方案中,本发明提供与三螺旋形式功能性核酸偶联的CD38BP。这种核酸分子可与双链或单链核酸相互作用。当三螺旋分子与靶区域相互作用时,形成了被称为三螺旋的结构,其中3条DNA链形成了基于Watson-Crick和Hoogsteen碱基配对的复合物。三螺旋分子可以高亲和性和特异性与靶区域结合。如何生成并使用与多种不同的靶分子相结合的三螺旋形式分子的代表性实施例可在以下非限制性美国专利列表中找到:US 5,176,996、US 5,645,985、US 5,650,316、US5,683,874、US 5,693,773、US 5,834,185、US 5,869,246、US 5,874,566和US 5,962,426。In one technical solution, the present invention provides CD38BP coupled to functional nucleic acid in triple helix form. Such nucleic acid molecules can interact with double-stranded or single-stranded nucleic acids. When a triple-helical molecule interacts with a target region, a structure known as a triple helix is formed, in which the three DNA strands form a complex based on Watson-Crick and Hoogsteen base pairing. Triple helix molecules can bind to target regions with high affinity and specificity. Representative examples of how to make and use molecules in triple helix form that bind to a variety of different target molecules can be found in the following non-limiting list of US patents: US 5,176,996, US 5,645,985, US 5,650,316, US 5,683,874, US 5,693,773 , US 5,834,185, US 5,869,246, US 5,874,566 and US 5,962,426.
在一个技术方案中,CD38BP与外源性指导序列偶联。外源性指导序列(EGSs)是与形成可被切割靶分子的Rnase P所识别的复合物的靶核酸分子相结合的分子。EGSs可被设计为特异性针对所选择的RNA分子。RNAse P在细胞中帮助转运RNA(tRNA)的加工。通过使用可使靶RNA:EGS复合物模拟为天然tRNA底物的EGS,可募集细菌RNAse P来实质切割任何RNA序列(参见,例如WO 92/03566和Forster andAltman,Science 238,407-409(1990)的讨论)。如何生成并使用EGS分子以促进多种不同靶分子剪切的代表性实施例可在以下非限制性美国专利列表中提供:US 5,168,053、US 5,624,824、US 5,683,873、US5,728,521、US 5,869,248和US 5,877,162。In one technical solution, CD38BP is coupled to an exogenous guide sequence. Exogenous guide sequences (EGSs) are molecules that bind to target nucleic acid molecules forming a complex that is recognized by RNase P, which cleaves the target molecule. EGSs can be designed to be specific for selected RNA molecules. RNAse P aids in the processing of transfer RNA (tRNA) in cells. Bacterial RNAse P can be recruited to cleave virtually any RNA sequence by using EGS, which allows the target RNA:EGS complex to mimic a natural tRNA substrate (see, e.g., WO 92/03566 and Forster and Altman, Science 238, 407-409 (1990). )discussion). Representative examples of how to generate and use EGS molecules to facilitate cleavage of a variety of different target molecules are provided in the following non-limiting list of U.S. patents: US 5,168,053, US 5,624,824, US 5,683,873, US 5,728,521, US 5,869,248, and US 5,877,162 .
在一个技术方案中,CD38BP可与诸如siRNA或其它RNAi分子(例如,约20-25个核苷酸的抑制性双链(ds)RNA分子)这样的干扰核酸分子偶联,它可针对并干扰诸如参与CD38介导的疾病或症状这样的基 因表达产物的靶基因表达产物的作用。在例如Nishikura,Cell.107(4).415-8(2001)、Fjose et al.,Biotechnol Annu Rev.7,31-57(2001)、Hanon,Nature 418,244-51(2002)、Brantl,Biochim Biophys Acta.1575(1-3),15-25(2002)、Tuschl,Chembiochem.2(4),239-45(2001)、Caplen,Expert Opin Biol Ther.3(4),575-86(2003)、Lu et al.,CurrOpin MoI Ther.5(3),225-34(2003)、Shuey et al.,Drug DiscovToday.7(20),1040-6(2002)、Shi,Trends Genet.19(1),9-12(2003)、Kovar et al.,SeminCancer Biol.13(4),275-81(2003)、Lavrey et al.,Curr Opin Drug Discov Devel.6(4),561-9(2003)、Clewey,CommunDis Public Health.6(2),162-3(2003)、Duxbury etal.,J Surg Res.117(2),339-44(2004)、Caplen et al.,Ann N Y Acad Sci.1002,56-62(2003)、WO 01/75164、US 6,506,559、US 20040086884、US20040077574、US 20040063654、US 20040033602、US 20030167490、US 20030157030、US 20030114409、US 20030108923、US20040014113和US 20020132788中提供了产生和使用干扰核酸分子的方法。In one technical solution, CD38BP can be conjugated to interfering nucleic acid molecules such as siRNA or other RNAi molecules (e.g., inhibitory double-stranded (ds) RNA molecules of about 20-25 nucleotides), which can target and interfere with Role of target gene expression products such as gene expression products involved in CD38-mediated diseases or conditions. In eg Nishikura, Cell. 107(4).415-8(2001), Fjose et al., Biotechnol Annu Rev.7, 31-57(2001), Hanon, Nature 418, 244-51(2002), Brantl, Biochim Biophys Acta.1575(1-3), 15-25(2002), Tuschl, Chembiochem.2(4), 239-45(2001), Caplen, Expert Opin Biol Ther.3(4), 575-86( 2003), Lu et al., CurrOpin MoI Ther.5(3), 225-34(2003), Shuey et al., Drug DiscovToday.7(20), 1040-6(2002), Shi, Trends Genet.19 (1), 9-12(2003), Kovar et al., Semin Cancer Biol.13(4), 275-81(2003), Lavrey et al., Curr Opin Drug Discov Devel.6(4), 561-9 (2003), Clewey, CommunDis Public Health.6(2), 162-3(2003), Duxbury et al., J Surg Res. 117(2), 339-44(2004), Caplen et al., Ann N Y Acad Sci.1002,56-62(2003)、WO 01/75164、US 6,506,559、US 20040086884、US20040077574、US 20040063654、US 20040033602、US 20030167490、US 20030157030、US 20030114409、US 20030108923、US20040014113和US 20020132788中提供了产生and methods of using interfering nucleic acid molecules.
在一个技术方案中,CD38BP可与肿瘤靶向结构域肽或分子偶联。在一个技术方案中,CD38BP与肿瘤靶向因子VII序列偶联。In one technical solution, CD38BP can be coupled to a tumor targeting domain peptide or molecule. In one technical solution, CD38BP is coupled to the sequence of tumor targeting factor VII.
用于将CD38BP与偶联分子相偶联的本领域中任何已知的方法,譬如如上所述的方法,均可使用,包括在Hunter et al.,Nature.144,945(1962)、David et al.,Biochemistry 13,1014(1974)、Pain et al.,J.Immunol.Meth.40,219(1981)和Nygren,J.Histochem.and Cytochem.30,407(1982)中所述的方法。可以任何合适的方式来实现连接/偶联。例如,共价连接可采用二硫键的形式(如果需要且合适的情况下),可将CD38BP构建为含有额外的半胱氨酸密码子,但需要它不干扰分子的CD38结合活性。具有修饰的CD38BP中半胱氨酸巯基基团反应性的毒素分子可与CD38BP肽形成免疫连接物。选择性地,可使用固相多肽技术直接向CD38BP中引入巯基基团。例如,Hiskey,Peptides 3,137(1981)描述了向肽中引入巯基的方法。在Maasen et al.,Eur.J.Biochem.134,32(1983)中描述了向蛋白中引入巯基的方法。当存在正确的巯基基团时,可纯化细胞毒素和CD38BP,二者的硫基被还原;细胞毒素和配体相混合(例如,以约1∶5到1∶20的比例);在室温下可完成二硫键的形成(通常约20到30分钟)。然后,可通过磷酸缓冲盐透析或诸如葡聚 糖这样的树脂进行层析来除去混合物中未反应的配体及毒素分子。Any method known in the art for conjugating CD38BP to a coupling molecule, such as those described above, can be used, including in Hunter et al., Nature. 144, 945 (1962), David et al. al., Biochemistry 13, 1014 (1974), Pain et al., J. Immunol. Meth. 40, 219 (1981) and Nygren, J. Histochem. and Cytochem. 30, 407 (1982). Linking/coupling can be accomplished in any suitable manner. For example, covalent linkage can take the form of a disulfide bond (if desired and appropriate), and CD38BP can be constructed to contain an additional cysteine codon, but only if it does not interfere with the CD38 binding activity of the molecule. Toxin molecules with modified cysteine sulfhydryl group reactivity in CD38BP can form immunoconjugates with CD38BP peptides. Alternatively, sulfhydryl groups can be introduced directly into CD38BP using solid phase peptide technology. For example, Hiskey, Peptides 3, 137 (1981) describes a method for introducing sulfhydryl groups into peptides. A method for introducing sulfhydryl groups into proteins is described in Maasen et al., Eur. J. Biochem. 134, 32 (1983). When the correct sulfhydryl group is present, cytotoxin and CD38BP can be purified with their thio groups reduced; cytotoxin and ligand are mixed (e.g., in a ratio of about 1:5 to 1:20); at room temperature Disulfide bond formation can be completed (usually about 20 to 30 minutes). Unreacted ligand and toxin molecules can then be removed from the mixture by phosphate buffered saline dialysis or chromatography on a resin such as dextran.
可通过细胞毒性组分上的反应基团或通过使用交联试剂将多种类型的细胞毒性组分加入到蛋白中。常用的可在体内与胺形成稳定共价键的反应基团是异硫氰酸盐(Meanset al.,Chemical modifications ofproteins(Holden-Day,San Francisco 1971)pp.105-110)。该基团优选地与赖氨酸的ε-氨基反应。顺丁烯二酰亚胺通常用作反应基团以在体内与半胱氨酸上的巯基基团形成稳定的共价键(Ji.,Methods Enzymol 91.,580-609(1983))。典型地,单克隆抗体不能与射电金属离子形成共价键,但它们间接通过使用与抗体共价连接的螯合剂来吸附在抗体上。螯合剂可通过氨基酸残基的氨基基团(Meares etal.,Anal.Biochem..142,68-78(1984))及巯基基团(Koyama,Chem.Abstr.120,217262t(1994)),也可通过碳水化合物基团(Rodwell et al.,PNAS USA 83,2632-2636(1986)、Quadri et al.,Nucl.Med.Biol.20,559-570(1993))连接。由于这些螯合剂含有两种类型的功能基团,一种结合金属离子,另一种参与抗体的螯合,因此它们通常称为双功能螯合剂(Sundberg et al.,Nature 250,587-588(1974))。Various types of cytotoxic components can be incorporated into proteins through reactive groups on the cytotoxic component or through the use of cross-linking reagents. A commonly used reactive group capable of forming stable covalent bonds with amines in vivo is isothiocyanate (Means et al., Chemical modifications of proteins (Holden-Day, San Francisco 1971) pp. 105-110). This group preferably reacts with the ε-amino group of lysine. Maleimide is commonly used as a reactive group to form a stable covalent bond with a sulfhydryl group on cysteine in vivo (Ji., Methods Enzymol 91., 580-609 (1983)). Typically, monoclonal antibodies are unable to form covalent bonds with radiometal ions, but they are adsorbed to antibodies indirectly through the use of chelating agents covalently attached to the antibodies. Chelating agent can pass amino group (Meares et al., Anal.Biochem..142,68-78 (1984)) and sulfhydryl group (Koyama, Chem.Abstr.120,217262t (1994)) of amino acid residue, also Attachment can be via carbohydrate groups (Rodwell et al., PNAS USA 83, 2632-2636 (1986), Quadri et al., Nucl. Med. Biol. 20, 559-570 (1993)). Since these chelators contain two types of functional groups, one that binds metal ions and the other that participates in the chelation of antibodies, they are often referred to as bifunctional chelators (Sundberg et al., Nature 250, 587-588( 1974)).
具有反应性的功能基团的交联试剂可分为同源双功能或异源双功能的。同源双功能交联试剂的实施例包括与巯基基团(Chen et al.,J BiolChem 266,18237-18243(1991))反应的双顺丁烯二酰亚胺(BMH),及与氨基基团(Browning et al.,J.Immunol.t43,1859-1867(1989))反应的乙烯基乙二醇(succini midylsucciate)(EGS)。异源双功能交联物的实施例包括马来酰亚胺苯甲酸-N-羟基琥珀酰亚胺酯(MBS)(Myers etal.,J.Immunol.Meth.1^1,129-142(1989))。这些方法比较简单,是常用的。Cross-linking reagents with reactive functional groups can be classified as homobifunctional or heterobifunctional. Examples of homologous bifunctional crosslinking reagents include bismaleimide (BMH) reacted with sulfhydryl groups (Chen et al., J BiolChem 266, 18237-18243 (1991)), and bismaleimide (BMH) reacted with amino groups succini midylsucciate (EGS) reacted with a group (Browning et al., J. Immunol. t43, 1859-1867 (1989)). Examples of heterobifunctional crosslinkers include maleimidobenzoic acid-N-hydroxysuccinimide ester (MBS) (Myers et al., J. Immunol. Meth. 191, 129-142 (1989 )). These methods are relatively simple and commonly used.
治疗性或诊断性试剂也可以,或选择性地通过形成二硫键连接在还原性抗体组分的铰链区。作为选择,这种肽可使用诸如3-(2-吡啶二巯基)丙酸N-羟基琥珀酰亚胺酯(SPDP)这样的异源双功能交联物连接到抗体组分上。Yu et al.,Int.J.Cancer 56,244(1994)。这类偶联方法的通用技术在本领域是已知的。参见例如,Wong,Chemistry OfProteinConjugation And Cross-Linking(CRC Press 1991)、Upeslacis et al.,″Modification of Antibodies by Chemical Methods,″In MonoclonalAntibodies:Principles And Applicatiohs,Birch et al.,(eds.)(Wiley- Liss,Inc.1995)、Price,″Production and Characterization of SyntheticPeptide-Derived Antibodies,″inMonoclonal Antibodies:Production,Engineering And Clinical Application,Ritteret al.,(eds.)(CambridgeUniversity Press 1995)。A therapeutic or diagnostic agent can also, or alternatively, be attached to the hinge region of the reducing antibody component by forming a disulfide bond. Alternatively, such peptides can be attached to the antibody component using a heterobifunctional cross-linker such as N-hydroxysuccinimidyl 3-(2-pyridyldithio)propionate (SPDP). Yu et al., Int. J. Cancer 56, 244 (1994). General techniques for such coupling methods are known in the art. See, for example, Wong, Chemistry Of Protein Conjugation And Cross-Linking (CRC Press 1991), Upeslacis et al., "Modification of Antibodies by Chemical Methods," In Monoclonal Antibodies: Principles And Applicatiohs, Birch et al., (eds.) (Wiley- Liss, Inc. 1995), Price, "Production and Characterization of Synthetic Peptide-Derived Antibodies," in Monoclonal Antibodies: Production, Engineering And Clinical Application, Ritter et al., (eds.) (Cambridge University Press 1995).
在某些技术方案中,标记或其它偶联的取代基团通过各种长度的间隔臂与CD38BP的氨基酸序列连接,以减小可能的立体位阻。In some technical solutions, labels or other coupled substituent groups are connected to the amino acid sequence of CD38BP through spacer arms of various lengths to reduce possible steric hindrance.
未标记的CD38BP(s)可与和CD38BP(s)反应的其它标记的抗体(第二抗体),例如,针对与抗CD38mAbs连接的人免疫球蛋白恒定区的抗体联合使用。选择性地,可直接标记CD38BP。多种标记可用于直接或间接标记CD38BPs,例如标记放射性核、氟石、酶、酶底物、酶辅因子、酶抑制剂、配体(特别是半抗原)等。Unlabeled CD38BP(s) can be used in combination with other labeled antibodies (secondary antibodies) reactive with CD38BP(s), eg, antibodies directed against human immunoglobulin constant regions linked to anti-CD38 mAbs. Alternatively, CD38BP can be directly labeled. A variety of labels can be used to directly or indirectly label CD38BPs, such as labeling radionuclei, fluorspar, enzymes, enzyme substrates, enzyme cofactors, enzyme inhibitors, ligands (especially haptens), etc.
氨基酸序列插入包括氨基和/或羧基末端融合长度为1个残基到含100或更多残基的多肽,及内部序列插入单个或多个氨基酸残基。末端插入的实施例包括具有N末端甲二磺酰残基的抗体或融合抗原决定簇标签的抗体。其它抗体分子的插入变异体包括抗体的N或C末端融合酶或多肽或PEG,从而增加抗体的血清半衰期。这种抗CD38抗体融合蛋白和类似的含CD38BP序列的融合蛋白是本发明的另一个特征。Amino acid sequence insertions include amino and/or carboxyl terminal fusions of 1 residue in length to polypeptides containing 100 or more residues, and internal sequence insertions of single or multiple amino acid residues. Examples of terminal insertions include antibodies with an N-terminal methionyl residue or antibodies fused to an epitope tag. Insertional variants of other antibody molecules include fusion of the N- or C-terminus of the antibody to an enzyme or polypeptide or PEG, thereby increasing the serum half-life of the antibody. Such anti-CD38 antibody fusion proteins and similar fusion proteins containing CD38BP sequences are another feature of the invention.

在一个技术方案中,本发明提供与混合毒素偶联的CD38BP。混合的毒素分子是来源于两个不同(典型地多肽)毒素的分子。通常,肽毒素含有一个或多个负责进行真核细胞结合的结构域,至少一个有酶活性的结构域,及至少一个转位结构域。结合和转位结构域分别是细胞识别和毒素进入所需的。已知具有转位结构域的天然蛋白包括白喉毒素、假单胞菌外毒素A和可能的其它肽毒素。白喉毒素和假单胞菌外毒素A 的转位结构域已被描述(参见,例如Hoch et al.,PNAS USA 82,1692(1985)、Colombatti et al.,J.Biol.Chem.26J.,3030(1986)和Deleerset al.,FEBS Lett.160,82(1983)),这种结构域在其它分子中的存在和定位可通过例如Hwang et al.,Cell 48,129(1987)和Gray et al.,PNASUSA 8J.2645(1984)进行的方法进行测定。对这些技术而言,有用的混合毒素杂交物可通过例如将有酶活性的大肠杆菌志贺样毒素的A亚基(Calderwood et al.,PNAS USA 84,4364(1987))与白喉毒素的转位结构域(氨基酸残基从202到460)与针对特定细胞类型的分子融合而形成,如US 5,906,820所述。三部分的杂和体的定位部分可使分子特异地结合到靶细胞上,白喉毒素转位部分可将志贺样毒素有酶活性的A亚基插入到靶细胞中。志贺样毒素有酶活性的部分与白喉毒素一样作用于细胞的蛋白合成机器,抑制蛋白合成,从而杀死靶细胞。In one technical solution, the present invention provides CD38BP coupled to mixed toxins. A mixed toxin molecule is a molecule derived from two different (typically polypeptide) toxins. Typically, a peptide toxin contains one or more domains responsible for eukaryotic cell binding, at least one enzymatically active domain, and at least one translocation domain. Binding and translocation domains are required for cellular recognition and toxin entry, respectively. Natural proteins known to have translocation domains include diphtheria toxin, Pseudomonas exotoxin A and possibly other peptide toxins. The translocation domains of diphtheria toxin and Pseudomonas exotoxin A have been described (see, for example, Hoch et al., PNAS USA 82, 1692 (1985), Colombatti et al., J. Biol. Chem. 26 J., 3030 (1986) and Deleers et al., FEBS Lett.160, 82 (1983)), the presence and location of this domain in other molecules can be ascertained by e.g. Hwang et al., Cell 48, 129 (1987) and Gray et al. al., PNASUSA 8J.2645 (1984) method carried out measurement. For these techniques, useful mixed toxin hybrids can be obtained by, for example, enzymatically active subunit A of E. coli Shiga-like toxin (Calderwood et al., PNAS USA 84, 4364 (1987)) and diphtheria toxin. The amino acid domain (from amino acid residues 202 to 460) is fused to a cell-type-specific molecule, as described in US 5,906,820. The localization part of the three-part hybrid can specifically bind the molecule to the target cell, and the diphtheria toxin translocation part can insert the enzymatically active A subunit of the Shiga-like toxin into the target cell. The enzymatically active part of Shiga-like toxin, like diphtheria toxin, acts on the protein synthesis machinery of cells, inhibits protein synthesis, and kills target cells.
如本发明所述的免疫连接物也可包含放射性同位素,例如碘-131、钇-90或铟-111,从而产生细胞毒性的放射性药物,用于治疗CD38相关的疾病,例如多发性骨髓瘤。Immunoconjugates according to the invention may also contain radioactive isotopes such as iodine-131, yttrium-90 or indium-111 to generate cytotoxic radiopharmaceuticals for the treatment of CD38-associated diseases such as multiple myeloma.
在一个技术方案中,诸如人抗体这样的本发明的CD38BPs与连接物-螯合剂,例如tiuxetan结合,从而使抗体与放射性同位素偶联。In one embodiment, CD38BPs of the invention, such as human antibodies, are conjugated to a linker-chelating agent, such as tiuxetan, thereby conjugating the antibody to a radioisotope.
其它有用的偶联物替代物包括抗肿瘤类维生素A。紫杉烷偶联物(参见,例如Jaimeet al.,Anticancer Res.21.(2A),1119-28(2001)、施铂锭偶联物、亚油酸偶联物、加里刹霉素偶联物(参见,例如Damle etal.,Curr Opin Pharmacol.3(4),386-90(2003)、阿霉素偶联物、格尔德霉素偶联物等也可用于促进癌症的治疗(通常参见Trail et al.,CancerImmunol Immunother.52(5),328-37(2003))。Other useful conjugate substitutes include antineoplastic retinoids. Taxane conjugates (see, e.g., Jaime et al., Anticancer Res. 21. (2A), 1119-28 (2001), platinum platinum conjugates, linoleic acid conjugates, calicheamicin conjugates Drugs (see, for example, Damle et al., Curr Opin Pharmacol. 3(4), 386-90 (2003), doxorubicin conjugates, geldanamycin conjugates, etc. can also be used to promote the treatment of cancer (usually See Trail et al., Cancer Immunol Immunother. 52(5), 328-37 (2003)).
在一个技术方案中,本发明提供针对本发明的抗CD38抗体的第二和抗独特型抗体。第二抗体是指特异,典型地针对抗CD38抗体的抗体。抗独特型(Id)抗体是识别通常与抗体的抗原结合位点相关的独特决定簇的抗体。可通过免疫具有制备抗Id的mAb的,与抗CD38mAb来源相同物种和基因型的动物来制备。典型地,免疫的动物可识别和对免疫抗体的独特型决定簇产生应答,从而产生针对这些独特型决定簇的抗体)抗Id抗体)。这种抗体描述在例如US 4,699,880中。这种抗体是本发明的另一个特征。In one embodiment, the present invention provides a second and anti-idiotypic antibody directed against the anti-CD38 antibody of the present invention. Secondary antibody refers to an antibody that is specific, typically against an anti-CD38 antibody. Anti-idiotypic (Id) antibodies are antibodies that recognize unique determinants normally associated with the antigen-binding site of an antibody. It can be prepared by immunizing an animal of the same species and genotype as the source of the anti-Id mAb. Typically, the immunized animal recognizes and responds to idiotypic determinants of the immunized antibody, thereby producing antibodies (anti-Id antibodies) directed against these idiotypic determinants. Such antibodies are described eg in US 4,699,880. Such antibodies are another feature of the invention.
抗Id抗体也可作为“免疫原”在另一种动物中诱导免疫应答,从而 产生所谓的抗抗Id抗体。抗抗Id可与原始的诱导抗Id的mAb具有相同的抗原决定簇。因此,通过使用针对mAb的独特型决定簇的抗体可鉴定其它具有相同特异性的克隆表达抗体。抗Id抗体可用任何合适的技术,例如本文其它地方描述的关于本发明的抗CD38抗体和其它CD38BPs的方法进行改变(从而产生抗Id抗体变异体)和/或衍生。例如,抗Id mAbs可与诸如钥孔血蓝蛋白(KLH)这样的载体偶联,并用于免疫BALB/c小鼠。来自这些小鼠的血清典型地含有具有与原始/母CD38抗体即使不同但相似的结合特性的抗抗Id抗体。Anti-Id antibodies can also be used as "immunogens" to induce an immune response in another animal, thereby producing so-called anti-anti-Id antibodies. The anti-anti-Id may have the same epitope as the original anti-Id-inducing mAb. Thus, by using antibodies directed against idiotypic determinants of mAbs, other clones expressing antibodies with the same specificity can be identified. Anti-Id antibodies can be altered (thus generating anti-Id antibody variants) and/or derivatized using any suitable technique, eg, as described elsewhere herein with respect to anti-CD38 antibodies and other CD38BPs of the invention. For example, anti-Id mAbs can be conjugated to a carrier such as keyhole limpet hemocyanin (KLH) and used to immunize BALB/c mice. Sera from these mice typically contain anti-anti-Id antibodies with similar, if different, binding properties to the original/parent CD38 antibodies.

The invention also provides one or more such immunogenic peptides and/or components of immunogenic peptide-encoding nucleic acids.
本发明的CD38BPs包括“内在化”CD38BPs,例如内在化抗体。术语“内在化CD38BP”和“内在化抗体”是指能实质抑制或消除CD38相关肽的生物学活性的CD38BP或抗体。典型地,内在化CD38BP,例如内在化抗CD38抗体可直接或间接抑制CD38的功能,例如酶活性、信号转导、诱导细胞因子表达、诱导增殖或分化或诱导裂解,在程度上比由于给药约等量的-003或-005或-024而使这种细胞的抑制更大。CD38BPs of the invention include "internalizing" CD38BPs, such as internalizing antibodies. The terms "internalizing CD38BP" and "internalizing antibody" refer to CD38BP or an antibody that substantially inhibits or eliminates the biological activity of CD38-related peptides. Typically, internalizing CD38BP, such as internalizing an anti-CD38 antibody, can directly or indirectly inhibit CD38 functions, such as enzymatic activity, signal transduction, induction of cytokine expression, induction of proliferation or differentiation, or induction of lysis, to a greater extent than due to administration of Approximately equal amounts of -003 or -005 or -024 resulted in greater inhibition of this cell.
本发明的CD38BP可对至少部分含在CD38中的一个或多个抗原决定簇具有任何合适的亲和性和/或强度。亲和性是指CD38BP与这种抗原决定簇结合的强度。典型地,亲和性通过解离常数Kd来测定,Kd定义为[Ab]×[Ag]/[Ab-Ag],其中[Ab-Ag]是抗体-抗原复合物(或CD38BP-抗原复合物)的摩尔浓度,[Ab]是未结合的抗体(或CD38BP)的摩尔浓度,[Ag]是未结合的抗原的摩尔浓度。亲和性常数Ka定义为1/Kd。通过竞争作用测定特异性和亲和性的合适方法可在例如,Harlow et al., Antibodies:A Laboratory Manual,Cold SpringHarbor Laboratory Press,Cold Spring Harbor,N.Y.,1988)、Colligan et al.,eds.,Current Protocolsin Immunology,Greene Publishing Assoc,and Wiley InterScienceN.Y.,(1992,1993)和Muller,Meth.Enzymol.92,589-601(1983)中发现。A CD38BP of the invention may have any suitable affinity and/or strength for one or more epitopes contained at least in part in CD38. Affinity refers to the strength with which CD38BP binds to this epitope. Typically, affinity is determined by the dissociation constant, Kd , defined as [Ab]×[Ag]/[Ab-Ag], where [Ab-Ag] is the antibody-antigen complex (or CD38BP -antigen complex), [Ab] is the molar concentration of unbound antibody (or CD38BP), and [Ag] is the molar concentration of unbound antigen. The affinity constant Ka is defined as 1/K d . Suitable methods for determining specificity and affinity by competition can be found, for example, in Harlow et al., Antibodies: A Laboratory Manual, Cold Spring Harbor Laboratory Press, Cold Spring Harbor, NY, 1988), Colligan et al., eds., Current Protocols in Immunology, Greene Publishing Assoc, and Wiley InterScience N.Y., (1992, 1993) and Muller, Meth. Enzymol. 92, 589-601 (1983).
CD38BP,特别是本发明的抗CD38抗体可具有至少部分含在CD38中的至少一个抗原决定簇的亲和性的范围为104到约1010M-1。典型地,此处术语免疫反应是指CD38BP与CD38抗原决定簇以解离常数Kd低于约10-4M的结合。CD38BPs, particularly anti-CD38 antibodies of the invention, may have an affinity for at least one epitope contained at least in part in CD38 in the range of 10 4 to about 10 10 M −1 . Typically, the term immune response herein refers to the binding of CD38BP to a CD38 epitope with a dissociation constant K d lower than about 10 -4 M.
CD38BP可具有至少与-003和-005和-024相同的针对CD38的亲和性,在某些技术方案中,具有至少与-003和-005和-024相同的亲和性。亲和性可通过任何其它地方所述的本领域中的方法或其已知的等同方法来测定。一个用于测定亲和性的方法的实施例在Scatchard analysis ofMunson & Pollard,Anal.Biochem.107,220(1980)中提供。结合亲和性也可通过平衡方法测定(例如,酶联免疫吸收检测方法(ELISA)或放射免疫检测(RIA)或动力学分析(例如BIACORETM分析)。The CD38BP may have at least the same affinity for CD38 as -003 and -005 and -024, and in some embodiments, at least the same affinity as -003 and -005 and -024. Affinity can be determined by methods in the art as described elsewhere or by known equivalent methods. An example of a method for determining affinity is provided in Scatchard analysis of Munson & Pollard, Anal. Biochem. 107, 220 (1980). Binding affinity can also be determined by equilibrium methods (eg, enzyme-linked immunosorbent assay (ELISA) or radioimmunoassay (RIA) or kinetic assays (eg, BIACORE ™ assay).
典型地,诸如抗CD38抗体这样的本发明的CD38BPs的解离常数小于约100nM、小于约50nM、小于约10nM、小于约5nM或更少、小于约1nM或更少、小于约0.5nM或更少、小于约0.1nM或更少、小于约0.01nM或更少、或甚至小于约0.001nM或更少。Typically, CD38BPs of the invention, such as anti-CD38 antibodies, have a dissociation constant of less than about 100 nM, less than about 50 nM, less than about 10 nM, less than about 5 nM or less, less than about 1 nM or less, less than about 0.5 nM or less , less than about 0.1 nM or less, less than about 0.01 nM or less, or even less than about 0.001 nM or less.
诸如抗CD38抗体这样的本发明的CD38BPs可具有与-003和-005和-024相同的功能特征,例如可通过抗体依赖的细胞毒素作用(ADCC)和补体介导的细胞毒素作用(CDC)检测法进行测定(参见,例如US5500362)。CD38BPs of the invention, such as anti-CD38 antibodies, may have the same functional characteristics as -003 and -005 and -024, e.g. detectable by antibody-dependent cytotoxicity (ADCC) and complement-mediated cytotoxicity (CDC) assay (see, eg, US5500362).
在一个技术方案中,如本发明所述的肽不作为CD38的竞争剂,而作为CD38的拮抗剂。CD38的竞争剂是可激活CD38一个或多个功能的分子。这种功能包括黏附中的受体介导和信号事件和(外部)酶活性。另外,作为外部酶,CD38以NAD+底物,形成环化ADP-核糖(cADPR)和ADPR,而且也生成尼克酰胺和尼克酰胺-腺苷二核苷磷酸(NAADP)。已表明cADPR作为Ca2+从内质网移动的第二信使。除了通过Ca2+的信号传导,CD38信号传导可通过与T和B细胞上的抗原-受体复合物或其它类型的受体复合物,例如MHC分子的交流而发生,并以这种方式参与到几种细胞应答中,而且也转换并分泌IgG1。In a technical solution, the peptide according to the invention does not act as a competitor of CD38, but as an antagonist of CD38. Competitors of CD38 are molecules that activate one or more functions of CD38. Such functions include receptor-mediated and signaling events in adhesion and (external) enzymatic activity. In addition, as an exogenous enzyme, CD38 forms cyclized ADP-ribose (cADPR) and ADPR with NAD + substrate, and also generates nicotinamide and nicotinamide-adenosine dinucleoside phosphate (NAADP). cADPR has been shown to act as a second messenger for the movement of Ca2 + from the endoplasmic reticulum. In addition to signaling through Ca2 + , CD38 signaling can occur through communication with antigen-receptor complexes on T and B cells or other types of receptor complexes, such as MHC molecules, and in this way participate in to several cellular responses and also converts and secretes IgG1.
在一个技术方案中,如本发明所述的肽不诱导PBMCs的显著增殖。在一个技术方案中,如本发明所述的肽不诱导IL-6水平的显著释放。在一个技术方案中,如本发明所述的肽不诱导可检测的IFN-γ水平的释放。这种检测可如Ausiello et al.,Tissue antigens56,538-547(2000)所述进行测定。In a technical solution, the peptides according to the invention do not induce significant proliferation of PBMCs. In one embodiment, the peptides according to the invention do not induce significant release of IL-6 levels. In one embodiment, the peptide according to the invention does not induce the release of detectable levels of IFN-γ. Such detection can be performed as described by Ausiello et al., Tissue antigens 56, 538-547 (2000).
本发明的抗CD38抗体和本发明的其它CD38BPs可通过重组表达在任何合适类型的细胞或动物中产生。Anti-CD38 antibodies of the invention and other CD38BPs of the invention can be produced by recombinant expression in any suitable type of cell or animal.

重组抗体,例如重组人抗体也包括从重组的组合的人抗体文库中分离的抗体、从动物,例如转基因动物分离的抗体,或通过任何其它包括将人免疫球蛋白编码核酸序列与其它人免疫球蛋白编码核酸和人免疫球蛋白编码基因外源的核酸序列拼接的方式制备、表达、产生或分离的抗体。典型地,重组人抗体具有来源于人胚系免疫球蛋白序列的可变区和恒定区。但在特定技术方案中,这种重组人抗体进行体外突变(或使用动物转基因的人Ig序列时进行体内体细胞突变),从而使重组抗体的VL和VL区的氨基酸序列是来源于人胚系VH和VL序列并与其相关,可以是在体内人抗体胚系库中非天然存在的序列。本发明提供了这两种类型的人抗体。Recombinant antibodies, such as recombinant human antibodies also include antibodies isolated from recombinant combinatorial human antibody libraries, antibodies isolated from animals, such as transgenic animals, or by any other method involving combining human immunoglobulin-encoding nucleic acid sequences with other human immunoglobulin Antibodies prepared, expressed, produced or isolated by splicing protein-encoding nucleic acid and exogenous nucleic acid sequence of human immunoglobulin-encoding gene. Typically, recombinant human antibodies have variable and constant regions derived from human germline immunoglobulin sequences. However, in a specific technical scheme, this recombinant human antibody undergoes in vitro mutation (or in vivo somatic mutation when animal transgenic human Ig sequences are used), so that the amino acid sequences of the VL and VL regions of the recombinant antibody are derived from human The germline VH and VL sequences, and related thereto, may be sequences that do not naturally occur in the human antibody germline repertoire in vivo. The present invention provides both types of human antibodies.

Monoclonal antibodies can be obtained by the hybridoma method first described in Kohler et al., Nature 256, 495 (1975), or by other known and subsequently developed methods (see, e.g., Goding, Monoclonal Antibodies: Principles and Practice, pp. 59 -103 (Academic Press, 1986)) prepared. Hybridomas useful for producing the anti-CD38 antibodies of the present invention are also provided in the present invention. Such hybridomas can be fused by chemical fusion, electrofusion or any other suitable technique with any suitable type of myeloma, heteromyeloma, lymphoblastoid, plasma cell or their equivalent and any suitable type of antibody expressing cell.

Such cells can be prepared using standard techniques, such as transformation with Epstein Barr virus or transforming genes (see, e.g., "Continuously Proliferating Human Cell Lines Synthesizing Antibody of Predetermined Specificity," Zurawaki, V.R. et al., in Monoclonal Antibodies, ed. by Kennett R.

含编码CD38BPs的外源核酸的重组细胞可通过任何合适的技术(例如,用裸露DNA质粒载体、病毒载体、侵入性细菌细胞载体或其它全细胞载体等转染/转化,包括通过磷酸钙沉淀的转染、受体介导的定位和转染、生物弹射击递送、电穿孔、葡聚糖介导的转染、脂质体介导的转化、原生质体融合、直接微注射等方法将CD38BP编码序列(或序列)递送到细胞中)制备。转化/转染细胞的方法是本领域已知的(参见,例如Sambrook et al.,MolecularCloning:A Laboratory Manual,ColdSpring Harbor Laboratory Press(2d Edition,1989 and 3rd Edition,2001)和F.Ausubel et al.,ed.Current Protocols inMolecular Biology,GreenePublishing and Wiley InterScience New York(1987)。这种重组细胞是本发明的一个特征。Recombinant cells containing exogenous nucleic acids encoding CD38BPs can be transfected/transformed by any suitable technique (e.g., with naked DNA plasmid vectors, viral vectors, invasive bacterial cell vectors, or other whole-cell vectors, including by calcium phosphate precipitation).

Ausubel et al. , ed. Current Protocols in Molecular Biology, Greene Publishing and Wiley InterScience New York (1987). Such recombinant cells are a feature of the present invention.
作为宿主用于重组蛋白蛋白的细胞系是本领域周知的,包括多种可从美国典型培养物保藏中心(ATCC)获得的永生化细胞系。这些细胞系中包括、中国仓鼠卵巢(CHO)细胞、NSO、SP2细胞、HeLa细胞、幼仓鼠肾(BHK)细胞、猴肾细胞(COS)、人肝癌细胞(例如Hep G2)、A549细胞及多种其它细胞系。其它可用的细胞系是诸如Sf9细胞这样的昆虫细胞系。当编码诸如CD38BPs(包括抗CD38抗体)这样的蛋白的核酸(或含核酸的载体)导入到哺乳动物宿主细胞中时,诸如CD38BPs这样的蛋白可通过将宿主细胞培养足以在宿主细胞中表达诸如CD38BPs这样的蛋白或将诸如CD38BPs这样的蛋白分泌到宿主细胞生长的培养基中的时间而产生。可用标准蛋白纯化方法从培养基中回收CD38BPs。当没有分泌信号而直接表达时,也可从宿主细胞裂解物中回收CD38BPs。Cell lines for use as hosts for recombinant proteins are well known in the art and include a variety of immortalized cell lines available from the American Type Culture Collection (ATCC). These cell lines include, Chinese hamster ovary (CHO) cells, NSO, SP2 cells, HeLa cells, baby hamster kidney (BHK) cells, monkey kidney cells (COS), human liver cancer cells (e.g. Hep G2), A549 cells and many more. other cell lines. Other useful cell lines are insect cell lines such as Sf9 cells. When a nucleic acid (or a nucleic acid-containing vector) encoding a protein such as CD38BPs (including an anti-CD38 antibody) is introduced into a mammalian host cell, the protein such as CD38BPs can be expressed in the host cell sufficiently by culturing the host cell such as CD38BPs Such proteins are produced when proteins such as CD38BPs are secreted into the medium in which the host cells are grown. CD38BPs can be recovered from the culture medium using standard protein purification methods. CD38BPs can also be recovered from host cell lysates when expressed directly without a secretion signal.
CD38BPs,例如抗CD38抗体,也可在细菌细胞和真核单细胞微生物,例如酵母中产生。产生诸如抗CD38抗体这样的CD38BPs的细菌细胞典型地缺少正常的糖基化,因此细菌细胞产生的抗CD38抗体或多或少会在哺乳动物细胞和/或动物中产生的抗CD38抗体相关的ADCC功能和其它免疫应答方面(例如,NK细胞的募集)有缺陷。酵母细胞产生的CD38BPs,例如抗CD38抗体通常具有与哺乳动物细胞中产生的抗体类型不同的糖基化模式。但在酵母中产生具有有效糖基化的抗体的方法目前已由公司,例如Glycofi,Inc.(Lebanon,NH,USA)开发出来。也参见Wildt S et al.,Nat Rev Microbiol.3(2),119-28(2005)。CD38BPs, such as anti-CD38 antibodies, can also be produced in bacterial cells and eukaryotic unicellular microorganisms, such as yeast. Bacterial cells that produce CD38BPs such as anti-CD38 antibodies typically lack normal glycosylation, so anti-CD38 antibodies produced by bacterial cells will more or less ADCC associated with anti-CD38 antibodies produced in mammalian cells and/or animals Functional and other aspects of the immune response (eg, recruitment of NK cells) are defective. CD38BPs produced in yeast cells, such as anti-CD38 antibodies, often have different glycosylation patterns than those produced in mammalian cells. However, methods for producing antibodies with efficient glycosylation in yeast have now been developed by companies such as Glycofi, Inc. (Lebanon, NH, USA). See also Wildt S et al., Nat Rev Microbiol. 3(2), 119-28 (2005).
当编码CD38BP基因(包括抗CD38抗体基因)的重组表达载体导入到哺乳动物宿主细胞中时,可通过将宿主细胞培养足以在宿主细胞中表达CD38BP或将抗体分泌到宿主细胞生长的培养基中的时间而产生CD38BPs。抗体和其它CD38BPs从细胞培养物、细胞裂解物和动物(例如,从产生抗CD38抗体的转基因动物的腹水液中)中的纯化可通过使用任何本领域已知的合适技术,例如免疫亲和柱纯化;硫酸盐沉淀;色谱聚焦;制备型SDS-PAGE等来完成。When a recombinant expression vector encoding a CD38BP gene (including an anti-CD38 antibody gene) is introduced into a mammalian host cell, it can be obtained by culturing the host cell enough to express CD38BP in the host cell or secrete the antibody into the growth medium of the host cell time to produce CD38BPs. Antibodies and other CD38BPs can be purified from cell cultures, cell lysates, and animals (e.g., from ascites fluid of transgenic animals producing anti-CD38 antibodies) by using any suitable technique known in the art, such as immunoaffinity columns Purification; sulfate precipitation; chromatographic focusing; preparative SDS-PAGE, etc. to complete.
本发明的人单克隆抗体也可通过各种其它技术,包括传统的单克隆抗体方法,例如Kohler and Milstein,Nature 256,495(1975)中所述的标准体细胞杂交技术来产生。其它产生单克隆抗体的技术也可使用,例如使用人抗体基因文库的噬菌体展示技术。在一个技术方案中,通过使用杂交瘤产生的本发明的抗CD38抗体在鼠系统中产生。在鼠中产生杂交瘤是非常成熟的流程。免疫流程和分离用于融合的免疫的脾细胞的技术是本领域已知的。融合部分(例如鼠骨髓瘤细胞)和融合程序也是已知的。Human monoclonal antibodies of the invention can also be produced by a variety of other techniques, including traditional monoclonal antibody methods, eg, standard somatic cell hybridization techniques as described in Kohler and Milstein, Nature 256, 495 (1975). Other techniques for producing monoclonal antibodies can also be used, such as phage display using human antibody gene libraries. In one embodiment, the anti-CD38 antibodies of the invention produced by using hybridomas are produced in a murine system. Generation of hybridomas in mice is a well-established procedure. Immunization protocols and techniques for isolating immunized splenocytes for fusion are known in the art. Fusion moieties (eg, murine myeloma cells) and fusion procedures are also known.
为了产生全长的针对CD38的人单克隆抗体,含人免疫球蛋白基因的转基因或转染色体鼠(例如HCo12、HCo7或KM鼠)可用CD38抗原和/或表达CD38的细胞的富集产物来免疫,例如,如Lonberg et al.,(1994)、同上,Fishwild et al.,(1996)、同上,及WO 98/24884所述。选择性地,可用编码人CD38的DNA免疫鼠。在第一次融合时鼠可以为6-16周龄。例如,CD38抗原的富集产物(5-50μg)可用于腹膜内免疫HuMAb鼠。在免疫过程中使用纯化的或富集的CD38抗原产物未产生抗体时,也可以用表达CD38的细胞,例如细胞系来免疫鼠,以促进免疫应答。To generate full-length human monoclonal antibodies directed against CD38, transgenic or transchromosomal mice containing human immunoglobulin genes (eg, HCo12, HCo7, or KM mice) can be immunized with CD38 antigen and/or enriched products of CD38-expressing cells , for example, as described in Lonberg et al., (1994), supra, Fishwild et al., (1996), supra, and WO 98/24884. Alternatively, mice can be immunized with DNA encoding human CD38. Mice can be 6-16 weeks old at first fusion. For example, an enriched product (5-50 μg) for CD38 antigen can be used to immunize HuMAb mice intraperitoneally. When antibodies are not produced during immunization using purified or enriched CD38 antigen products, CD38-expressing cells, such as cell lines, can also be used to immunize mice to promote an immune response.
使用各种抗原的积累经验表明,当用含在完全弗氏佐剂中的CD38表达细胞进行腹膜内(i.p.)或皮下(s.c.)初始免疫,然后每隔1周用含在PBS中的CD38表达细胞进行i.p.免疫(共10次以上),可以在HuMAb转基因鼠中产生最大的应答。可在免疫流程中用眶后采血获得的血浆样品来监测免疫应答。可通过FACS分析筛选血浆,具有足够滴度的抗CD38人免疫球蛋白的鼠可用于融合。鼠可在处死并除去脾的3天前用CD38表达细胞进行静脉内注射,如实施例4所述。Accumulated experience with various antigens shows that when priming intraperitoneally (i.p.) or subcutaneously (s.c.) with CD38-expressing cells in complete Freund's adjuvant, followed by CD38-expressing cells in PBS every other week Cells were i.p. immunized (more than 10 times in total) to generate the greatest response in HuMAb transgenic mice. Immune responses can be monitored during the immunization protocol using plasma samples obtained by retro-orbital bleeding. Plasma can be screened by FACS analysis and mice with sufficient titers of anti-CD38 human immunoglobulin can be used for fusions. Mice can be injected intravenously with CD38 expressing cells, as described in Example 4, 3 days before sacrifice and removal of the spleen.
为了产生可生产针对人CD38的人单克隆抗体的杂交瘤,从免疫鼠中分离脾细胞和淋巴结细胞,并与合适的永生化细胞系,例如鼠骨髓瘤细胞系融合。然后筛选可产生抗原特异的抗体的杂交瘤。例如,将来自免疫鼠的脾淋巴细胞的单细胞悬液与SP2/0非分泌鼠骨髓瘤细胞(ATCC,CRL 1581)用50%PEG(w/v)融合。在平底微孔板中放置细胞,每孔约1×105,然后在除通用试剂外,含10%胎克隆血清、5-10%Origen杂交瘤克隆因子(IGEN)1×HAT(Sigma)的选择培养基中培养2周。约2周后,可在用HT替换HAT的培养基中培养细胞。然后通过针对含κ-轻链的抗体的ELISA和通过使用具有CD38特异性的CD38表达细胞的FACS分析来筛选各个孔。当大量的杂交瘤生长时,在10-14天后观察培养基。可重新放置分泌抗体的杂交瘤,再次筛选,如果对人IgG仍为阳性,则可将抗CD38单克隆抗体通过有限稀释至少亚克隆2次。然后在体外培养稳定的亚克隆,以在组织培养基中产生用于鉴定的抗体。To generate hybridomas producing human monoclonal antibodies directed against human CD38, splenocytes and lymph node cells are isolated from immunized mice and fused with a suitable immortalized cell line, such as a murine myeloma cell line. Hybridomas are then screened for the production of antigen-specific antibodies. For example, single cell suspensions of splenic lymphocytes from immunized mice were fused with SP2/0 non-secreting murine myeloma cells (ATCC, CRL 1581) with 50% PEG (w/v). Place the cells in a flat-bottomed microplate, about 1×10 5 per well, and then in addition to the common reagents, contain 10% fetal clone serum, 5-10% Origen hybridoma cloning factor (IGEN) 1×HAT (Sigma) Cultured in selective medium for 2 weeks. After about 2 weeks, the cells can be cultured in medium replacing HAT with HT. Individual wells were then screened by ELISA against kappa-light chain containing antibodies and by FACS analysis using CD38 expressing cells with CD38 specificity. The medium was observed after 10-14 days when a large number of hybridomas had grown. Antibody-secreting hybridomas can be relocated and screened again, and if they are still positive for human IgG, anti-CD38 monoclonal antibodies can be subcloned at least twice by limiting dilution. Stable subclones are then cultured in vitro to produce antibodies for characterization in tissue culture medium.
本发明的人抗体也可在宿主细胞转染瘤中联合使用例如本领域已知的重组DNA技术和基因转染方法来产生,参见例如Morrison,S., Science 229,1202(1985)。Human antibodies of the invention can also be produced in host cell transfectomas using, for example, combinations of recombinant DNA techniques and gene transfection methods known in the art, see, eg, Morrison, S., Science 229, 1202 (1985).
例如,为了表达抗体或其抗体片段,可通过标准分子生物学技术(例如PCR、定点突变)获得编码部分或全长轻链和重链的DNAs,并将其插入到表达载体中,从而使基因与转录和翻译控制序列可操作连接。在本文中,术语“可操作连接”是指抗体基因与载体连接,从而使载体中的转录和翻译控制序列行使调控抗体基因的转录和翻译的功能。表达载体和表达控制序列选择为与所用的表达宿主细胞兼容的序列。可将抗体轻链基因和抗体重链基因插入到不同载体中,或更典型地,两个基因插入到相同的表达载体中。可通过标准方法(例如,抗体基因片段和载体的互补限制性位点的连接,或如果不存在限制性位点,则进行平末端连接)将抗体基因插入到表达载体中。此处所述的抗体轻链和重链可变区可通过将任何抗体同种型的全长抗体基因插入到已有编码所需同种型的重链恒定区和轻链恒定区的表达载体中,从而使VH片段与载体中的CH片段可操作连接,VL片段与载体中的CL片段可操作连接而获得。另外,或选择性地,重组表达载体可编码利于抗体链从宿主细胞中分泌的信号肽。可将抗体链基因克隆到载体中,从而使信号肽同框连接到抗体链基因的氨基末端。信号肽可以是免疫球蛋白的信号肽或异源信号肽(例如,来自非免疫球蛋白的蛋白信号肽)。For example, to express an antibody or antibody fragment thereof, DNAs encoding partial or full-length light and heavy chains can be obtained by standard molecular biology techniques (e.g., PCR, site-directed mutagenesis) and inserted into expression vectors so that the genes Operably linked to transcriptional and translational control sequences. Herein, the term "operably linked" means that the antibody gene is linked to the carrier, so that the transcription and translation control sequences in the carrier can perform the function of regulating the transcription and translation of the antibody gene. The expression vector and expression control sequences are selected to be those compatible with the expression host cell used. The antibody light chain gene and the antibody heavy chain gene can be inserted into separate vectors or, more typically, both genes are inserted into the same expression vector. Antibody genes can be inserted into expression vectors by standard methods (eg, ligation of antibody gene fragments and complementary restriction sites of the vector, or blunt end ligation if no restriction sites are present). The antibody light and heavy chain variable regions described herein can be obtained by inserting the full-length antibody gene of any antibody isotype into an existing expression vector encoding the heavy and light chain constant regions of the desired isotype , so that the VH segment is operably linked to the CH segment in the vector, and the VL segment is operably linked to the CL segment in the vector. Additionally, or alternatively, the recombinant expression vector may encode a signal peptide that facilitates secretion of the antibody chain from the host cell. The antibody chain genes can be cloned into a vector such that the signal peptide is linked in-frame to the amino terminus of the antibody chain genes. The signal peptide can be that of an immunoglobulin or a heterologous signal peptide (eg, a signal peptide from a protein other than an immunoglobulin).
除了抗体链基因,本发明的重组表达载体可携带调控抗体链基因在宿主细胞中表达的调控序列。In addition to antibody chain genes, the recombinant expression vector of the present invention can carry regulatory sequences that regulate the expression of antibody chain genes in host cells.
除了抗体链基因和调控序列外,本发明的重组表达载体可携带其它序列,例如调控载体在宿主细胞中复制的序列(例如复制起点)和选择标记基因。选择标记基因利于在引入载体的宿主细胞中进行筛选(参见例如US 4,399,216、US 4,634,665和US 5,179,017)。例如,典型地,选择标记基因可在引入载体的宿主细胞中赋予对药物,例如G418、潮霉素或甲氨蝶呤的抗性。选择标记基因的例子包括二氢叶酸还原酶(DHFR)基因(用于在dhfr宿主细胞中用甲氨蝶呤筛选/扩增)和neo基因(用于G418筛选)。In addition to antibody chain genes and regulatory sequences, the recombinant expression vectors of the present invention may carry other sequences, such as sequences that regulate replication of the vector in host cells (eg, origin of replication) and selectable marker genes. A selectable marker gene facilitates selection in the host cell into which the vector is introduced (see eg US 4,399,216, US 4,634,665 and US 5,179,017). For example, a selectable marker gene typically confers resistance to a drug, such as G418, hygromycin, or methotrexate, in the host cell into which the vector is introduced. Examples of selectable marker genes include the dihydrofolate reductase (DHFR) gene (for selection/amplification with methotrexate in dhfr host cells) and the neo gene (for G418 selection).
为了表达轻链和重链,将编码重链和轻链的表达载体通过标准技术转染到宿主细胞中。宿主细胞可以是原核或真核宿主细胞,例如哺乳动物。例如,可在原核宿主细胞中表达抗原结合片段,在真核宿主细胞中表达全长抗体。To express the light and heavy chains, expression vectors encoding the heavy and light chains are transfected into host cells by standard techniques. The host cell can be a prokaryotic or eukaryotic host cell, such as a mammal. For example, antigen-binding fragments can be expressed in prokaryotic host cells and full-length antibodies can be expressed in eukaryotic host cells.
在一个技术方案中,抗体在真核细胞,例如哺乳动物宿主细胞中表达。在哺乳动物宿主细胞中表达本发明的重组抗体的实施例包括CHO细胞(包括dhfr-CHO细胞,在Urlauband Chasin,PNAS USA 77,4216-4220(1980)描述,以DHFR为筛选标记,例如在R.J.KaufmanandP.A.Sharp,MoI.Biol.159,601-621(1982)中描述)、NS/O骨髓瘤细胞、COS细胞、HEK293细胞和SP2.0细胞。特别是使用NS/O骨髓瘤细胞,表达系统的另一个实施例是GS(谷氨酸合成酶)基因表达系统,在WO87/04462、WO89/01036和EP338841中描述。In one embodiment, antibodies are expressed in eukaryotic cells, such as mammalian host cells. Examples of expressing the recombinant antibody of the present invention in mammalian host cells include CHO cells (including dhfr-CHO cells, described in Urlauband Chasin, PNAS USA 77, 4216-4220 (1980), using DHFR as a selection marker, such as in R.J. Kaufman and P.A. Sharp, MoI. Biol. 159, 601-621 (1982) described), NS/O myeloma cells, COS cells, HEK293 cells and SP2.0 cells. Another example of an expression system, particularly using NS/O myeloma cells, is the GS (glutamate synthetase) gene expression system described in WO87/04462, WO89/01036 and EP338841.
可在其它表达系统,包括原核细胞,例如微生物,例如产生scFv抗体的大肠杆菌、藻类和昆虫细胞中表达CD38BP。另外,可在转基因非人动物,例如羊和兔奶或鸡蛋,或转基因植物中表达CD38BPs。参见例如Verma,R.et al.,J.lmmunol.Meth.216,165-181(1998)、Pollocket al.,J.lmmunol.Meth.23J.,147-157(1999)和Fischer,R.et al.,Biol.Chem.380,825-839(1999)。CD38BP can be expressed in other expression systems, including prokaryotic cells, such as microorganisms such as E. coli, algae and insect cells that produce scFv antibodies. Additionally, CD38BPs can be expressed in transgenic non-human animals, such as sheep and rabbit milk or eggs, or in transgenic plants. See eg Verma, R. et al., J. Immunol. Meth. 216, 165-181 (1998), Pollock et al., J. Immunol. Meth. 23 J., 147-157 (1999) and Fischer, R. et al., Biol. Chem. 380, 825-839 (1999).
本发明的双特异性和多特异性CD38BPs可通过化学技术、“Polydoma”技术(参见US4,474,893)或重组DNA技术制备(参见例如D.M.Kranz et al.,PNAS USA 78,5807(1981))。The bispecific and multispecific CD38BPs of the invention can be prepared by chemical techniques, "Polydoma" techniques (see US 4,474,893) or recombinant DNA techniques (see eg D.M. Kranz et al., PNAS USA 78, 5807 (1981)).
本发明的双特异性抗体可通过各种已知的方法,包括杂交瘤融合或Fab′片段连接(参见,例如Songsivilai&Lachmann,Clin.Exp.Immunol.79,315-321(1990)和Kostelny etal.,J.Immunol.M8,1547-1553(1992))来产生。传统地,双特异性抗体的重组产生是基于两个免疫球蛋白重链-轻链对的共表达,其中两个重链具有不同的特异性(参见例如,Milsteinand Cuello,Nature 305,537(1983))。由于免疫球蛋白重链和轻链的随机分选,这些杂交瘤(四源杂交瘤)可产生约10中不同抗体分子的混合物,其中只有一种具有正确的双特异性结构。类似流程在WO93/08829和Traunecker et al.,EMBO J.10,3655(1991)中描述。The bispecific antibody of the present invention can be obtained by various known methods, including fusion of hybridomas or linking of Fab' fragments (see, for example, Songsivilai & Lachmann, Clin. Exp. Immunol. 79, 315-321 (1990) and Kostelny et al., J. Immunol. M8, 1547-1553 (1992)) to produce. Traditionally, the recombinant production of bispecific antibodies is based on the co-expression of two immunoglobulin heavy chain-light chain pairs, where the two heavy chains have different specificities (see, e.g., Milstein and Cuello, Nature 305, 537 (1983 )). Due to the random sorting of immunoglobulin heavy and light chains, these hybridomas (quadromas) produce a mixture of about 10 different antibody molecules, only one of which has the correct bispecific structure. Similar procedures are described in WO93/08829 and Traunecker et al., EMBO J. 10, 3655 (1991).
根据不同的方法,将具有所需结合特异性的抗体可变结构域(抗体-抗原结合位点)与免疫球蛋白恒定结构域序列通过重组或合成方法融合在一起。可变结构域序列典型地与含至少部分铰链、CH2和CH3区的免疫球蛋白重链恒定结构域融合。而且典型地,在融合肽中至少也存在一个含轻链结合所需位点的第一重链恒定区(CH1)。在这种方法的具体实施例中,产生的双特异性抗体含有在一个臂具有第一结合特异性的免 疫球蛋白重链的杂交体,另一个臂为免疫球蛋白重链-轻链对(提供第二结合特异性)的杂交体。这种非对称结构可利于从不需要的免疫球蛋白链组合中分离所需的双特异性化合物(这种方法描述在WO94/04690中)。对产生双特异性抗体的进一步细节,参见例如Suresh et al.,MethodsinEnzymology 121,210(1986)。According to different approaches, antibody variable domains (antibody-antigen combining sites) with the desired binding specificities are fused to immunoglobulin constant domain sequences by recombinant or synthetic methods. The variable domain sequences are typically fused to an immunoglobulin heavy chain constant domain comprising at least part of the hinge, CH2 and CH3 regions . And typically, at least one first heavy chain constant region ( CH1 ) containing the site required for light chain binding is also present in the fusion peptide. In specific embodiments of this method, bispecific antibodies are produced that contain a hybrid of an immunoglobulin heavy chain with a first binding specificity in one arm and an immunoglobulin heavy chain-light chain pair ( providing a hybrid of the second binding specificity). This asymmetric structure may facilitate the separation of desired bispecific compounds from unwanted combinations of immunoglobulin chains (this approach is described in WO94/04690). For further details on the production of bispecific antibodies see, eg, Suresh et al., Methods in Enzymology 121, 210 (1986).
在另一种方法中,一对抗体分子的交界处通过构建以使从重组细胞培养物中回收的异源二聚体,从而形成双特异性抗体分子群的比例最大化。典型地,这种交界处含至少一部分抗体恒定区的CH3结构域。通常在这种方法中,将第一抗体分子交界处的一个和多个具有较小的侧链的氨基酸残基用具有较大侧链的氨基酸残基(例如酪氨酸或色氨酸)替代。通过用较小残基(例如丙氨酸或苏氨酸)替代较大氨基酸侧链残基,则在第二抗体分子交界处产生与大侧链氨基酸残基具有相同或相似大小的补偿性“洞穴”。这可增加异源二聚体而不是其它不需要的诸如同源二聚体这样的终产物的产量。In another approach, the junction of a pair of antibody molecules is engineered to maximize the proportion of heterodimers recovered from recombinant cell culture, thereby forming the population of bispecific antibody molecules. Typically, this junction comprises at least a portion of the CH3 domain of an antibody constant region. Typically in this approach, one or more amino acid residues with smaller side chains at the junction of the first antibody molecule are replaced with amino acid residues with larger side chains (such as tyrosine or tryptophan) . By substituting smaller residues (such as alanine or threonine) for larger amino acid side chain residues, a compensatory "compensatory" amino acid residue of the same or similar size as the large side chain amino acid residue is created at the junction of the second antibody molecule cave". This increases the yield of heterodimers rather than other unwanted end products such as homodimers.
本发明的双特异性和多特异性分子可通过本领域已知的方法偶联具有结合特异性,例如抗FcR和抗CD38结合特异性的构建体而制备。当结合特异性是蛋白或肽时,可使用各种偶联或交联试剂进行共价偶联。交联试剂的实施例包括蛋白A、碳二亚胺、S-乙酰基-巯基乙酸N-羟基丁二酰亚胺酯(SATA)、5,5′双(4-硝基-3-羧基苯)二硫化物(DTNB)、o-亚苯基顺丁烯二酰亚胺(oPDM)、3-(2-吡啶二巯基)丙酸N-羟基琥珀酰亚胺酯(SPDP)和磺基琥珀酰亚胺基4-[马来酰亚胺甲基]-环己烷-1羧酸盐(sulfo-SMCC),参见,例如Karpovsky etal.,J.Exp.Med.160,1686(1984)、Liu,M.A.et al.,PNAS USA 82,8648(1985)。在另一个实施例中,Brennan et al.,Science 229,81(1985)描述了将完整抗体蛋白酶裂解产生F(ab′)2片段的流程。这些片段在存在可稳定邻近二硫,并抑制分子内二硫键形成的巯醇配位试剂亚砷酸钠时被还原。然后将产生的Fab′片段转变为硝基苯甲酸(TNB)衍生物。然后将其中一种Fab′-TNB衍生物通过用半胱胺还原再次转变为Fab′-巯醇,并与等量的其它Fab′-TNB衍生物混合而形成双特异性抗体。Shalabyet al.,J.Exp.Med.175,217-225(1992)根据相关技术,描述了完全人源化双特异性抗体F(ab′)2分子的产生。其它方法包括那些Paulus(Behring Ins.Mitt.No.78,118-132(1985))和Glennie et al.,J.Immunol. 139,2367-2375(1987)描述的方法。偶联试剂的实施例有SATA和sulfo-SMCC,均可从Pierce ChemicalCo.(Rockford,IL)获得。Bispecific and multispecific molecules of the invention can be prepared by conjugating constructs with binding specificities, such as anti-FcR and anti-CD38 binding specificities, by methods known in the art. When the binding specificity is a protein or peptide, various coupling or cross-linking reagents can be used for covalent coupling. Examples of crosslinking reagents include protein A, carbodiimide, N-hydroxysuccinimide S-acetyl-thioglycolate (SATA), 5,5'bis(4-nitro-3-carboxyphenyl ) disulfide (DTNB), o-phenylenemaleimide (oPDM), 3-(2-pyridyldimercapto)propionic acid N-hydroxysuccinimide ester (SPDP) and sulfosuccinate Imido 4-[maleimidomethyl]-cyclohexane-1 carboxylate (sulfo-SMCC), see, for example, Karpovsky et al., J. Exp. Med. 160, 1686 (1984), Liu, MA et al., PNAS USA 82, 8648 (1985). In another example, Brennan et al., Science 229, 81 (1985) describe a procedure for the proteolytic cleavage of intact antibodies to generate F(ab') 2 fragments. These fragments are reduced in the presence of the thiol complexing reagent sodium arsenite, which stabilizes adjacent disulfides and inhibits intramolecular disulfide bond formation. The resulting Fab' fragments are then converted to nitrobenzoic acid (TNB) derivatives. One of the Fab'-TNB derivatives was then reconverted to Fab'-thiol by reduction with cysteamine and mixed with an equal amount of the other Fab'-TNB derivative to form a bispecific antibody. Shalaby et al., J. Exp. Med. 175, 217-225 (1992) describe the generation of fully humanized bispecific antibody F(ab') 2 molecules according to the related art. Other methods include those described by Paulus (Behring Ins. Mitt. No. 78, 118-132 (1985)) and Glennie et al., J. Immunol. 139, 2367-2375 (1987). Examples of coupling reagents are SATA and sulfo-SMCC, both available from Pierce Chemical Co. (Rockford, IL).
当结合特异性是抗体时,它们可通过两个重链铰链区的C末端巯基键偶联。在一个技术方案中,可在偶联前修饰铰链区使其含奇数数目例如1个的巯基残基。When the binding specificities are antibodies, they can be coupled via the C-terminal sulfhydryl bonds of the hinge regions of the two heavy chains. In one embodiment, the hinge region can be modified to contain an odd number, eg, 1, of sulfhydryl residues prior to conjugation.
选择性地,两种结合特异性可在同一个载体上编码,并在同一个宿主细胞中表达和组装。这种方法在双特异性和多特异性分子是mAb×mAb、mAb×Fab、Fab×F(ab′)2或配体×Fab融合蛋白时特别有用。本发明的双特异性和多特异性分子,例如双特异性分子可以是单链分子,例如单链双特异性抗体、含一个单链抗体和结合决定簇的双特异性分子,或含两个结合决定簇的单链双特异性分子。双特异性和多特异性分子也可以是单链分子或可含有至少两个单链分子。制备双和多特异性分子的方法在例如US 5,260,203、US 5,455,030、US4,881,175、US5,132,405、US 5,091,513、US 5,476,786、US 5,013,653、US 5,258,498和US5,482,858中描述。Alternatively, both binding specificities can be encoded on the same vector, expressed and assembled in the same host cell. This approach is particularly useful when the bispecific and multispecific molecules are mAbxmAb, mAbxFab, FabxF(ab') 2 or LigandxFab fusion proteins. The bispecific and multispecific molecules of the invention, e.g., bispecific molecules, can be single chain molecules, e.g., single chain bispecific antibodies, bispecific molecules comprising a single chain antibody and a binding determinant, or comprising two Single-chain bispecific molecules that bind determinants. Bispecific and multispecific molecules can also be single-chain molecules or can contain at least two single-chain molecules. Methods of making bi- and multispecific molecules are described, for example, in US 5,260,203, US 5,455,030, US 4,881,175, US 5,132,405, US 5,091,513, US 5,476,786, US 5,013,653, US 5,258,498 and US 5,482,858.
已描述了各种直接从重组细胞培养物中制备和分离双特异性抗体片段的技术。例如,可通过亮氨酸拉链产生双特异性抗体(参见,例如Kostelny et al.,J.Immunol.148(5),1547-1553(1992))。来自Fos和Jun蛋白的亮氨酸拉链肽可与两个不同抗体的Fab′部分通过基因融合而连接,得到的抗体同源二聚体在铰链区还原,从而形成可重新氧化的单体,以形成抗体异源二聚体。在中Hollinger et al.,PNAS USA 90,6444-6448(1993)描述的“双功能抗体”技术也提供了制备双特异性抗体片段的选择方案。已报道另一种使用单链Fv(sFv)二聚体制备双特异性抗体片段的策略是。参见例如Gruber et al.,J.Immunol.152,5368(1994)。Various techniques have been described for the preparation and isolation of bispecific antibody fragments directly from recombinant cell culture. For example, bispecific antibodies can be generated via leucine zippers (see, eg, Kostelny et al., J. Immunol. 148(5), 1547-1553 (1992)). Leucine zipper peptides from the Fos and Jun proteins can be linked by gene fusion to the Fab' portions of two different antibodies, and the resulting antibody homodimers are reduced at the hinge region to form reoxidizable monomers to Formation of antibody heterodimers. The "bifunctional antibody" technique described in Hollinger et al., PNAS USA 90, 6444-6448 (1993) also provides an option for preparing bispecific antibody fragments. Another strategy for preparing bispecific antibody fragments using single-chain Fv (sFv) dimers has been reported. See eg Gruber et al., J. Immunol. 152, 5368 (1994).
另外,双特异性抗体可形成“双功能抗体”(Holliger et al.,PNASUSA,90,6444-6448(1993))或“Janusins”(Traunecker et al.,EMBOJ10,3655-3659(1991)和Trauneckeret al.,lnt J Cancer Suppl 7,51-52(1992))。定义的双特异性抗体不存在具有单个结合位点的片段形式(例如Fab、Fab′和Fv片段,也由本发明提供)。Alternatively, bispecific antibodies can form "diabodies" (Holliger et al., PNASUSA, 90, 6444-6448 (1993)) or "Janusins" (Traunecker et al., EMBOJ10, 3655-3659 (1991) and Trauneckeret al., Int J Cancer Suppl 7, 51-52 (1992)). A defined bispecific antibody does not exist in fragment form with a single binding site (eg Fab, Fab' and Fv fragments, also provided by the present invention).
双特异性和多特异性分子与其靶标的结合可通过酶联免疫吸收测定法(ELISA)、放射性免疫检测(RIA)、FACS分析、生物检测(例 如生长抑制)或Western印迹检测法来确定。这些方法每种通常都是通过使用针对目的复合物的标记试剂(例如抗体)检测目的蛋白-抗体复合物的存在。例如,FcR-抗体复合物可用例如识别和特异结合抗体-FcR复合物的酶联抗体或抗体片段来检测。选择性地,可通过任何其它各种免疫检测法来检测复合物。例如,抗体可进行放射性标记,使用放射性免疫检测法(RIA)来检测(参见,例如Weintraub,B.,Principles ofRadioimmunoassays,Seventh Training Course on RadioligandAssayTechniques,The Endocrine Society,March,1986)。在这种方法中,使用γ计数器或闪烁计数器或通过自显影来检测放射性同位素。Binding of bispecific and multispecific molecules to their targets can be determined by enzyme-linked immunosorbent assay (ELISA), radioimmunoassay (RIA), FACS analysis, biological assays (e.g., growth inhibition), or Western blot assays. Each of these methods typically detects the presence of a protein-antibody complex of interest by using a labeled reagent (eg, an antibody) directed against the complex of interest. For example, an FcR-antibody complex can be detected using, for example, an enzyme-linked antibody or antibody fragment that recognizes and specifically binds to the antibody-FcR complex. Alternatively, the complex can be detected by any other various immunoassays. For example, antibodies can be radiolabeled and detected using radioimmunoassays (RIA) (see, e.g., Weintraub, B., Principles of Radioimmunoassays, Seventh Training Course on Radiolig and Assay Techniques, The Endocrine Society, March, 1986). In this method, radioisotopes are detected using a gamma counter or scintillation counter or by autoradiography.
如前所述,抗体主要通过位于六个重链和轻链互补决定区(CDRs)的氨基酸残基与靶抗原相互作用。本发明提供具有与来源于-003或-005或-024的CDR区相同或其衍生的CDR区的抗体。这种抗体可通过构建包括将来自-003或-005或-024的CDR序列移植到具有不同特性的不同抗体的框架序列中的表达载体而产生。As mentioned earlier, antibodies interact with target antigens primarily through amino acid residues located in the six heavy and light chain complementarity determining regions (CDRs). The present invention provides an antibody having a CDR region identical to or derived from a CDR region derived from -003 or -005 or -024. Such antibodies can be produced by constructing expression vectors comprising grafting of CDR sequences from -003 or -005 or -024 into the framework sequences of different antibodies with different properties.
这种框架序列可从含胚系抗体基因序列的公共DNA数据库获得。这些胚系序列由于不完全包括在B细胞成熟时通过V(D)J连接形成的组装可变基因,因此不同于成熟抗体基因序列。胚系基因序列也不同于在可变基因,典型地集中在CDRs中的高亲和力的第二抗体的序列。例如,体细胞突变在框架区1的氨基末端部分和框架区4的羧基末端部分相对较少。因此,不需获得特定抗体完整的DNA序列来重新产生完整的具有与原始抗体相似结合化学的重组抗体(参见WO 99/45962)。部分跨越CDR区的重链和轻链序列用于测定参与重组抗体可变基因中的胚系可变和连接基因片段。然后用胚系序列填充可变区的缺失部分。重链和轻链引导序列在蛋白成熟时被切割,不参与最终抗体的特性。为了增加缺失的序列,将克隆的cDNA序列与合成的寡核苷酸通过连接或PCR扩增进行连接。选择性地,完整的可变区可通过合成为一组短的重叠的寡核苷酸,并通过PCR合并而产生完整的合成的可变区克隆。该过程具有特定的优势,例如可删除或插入特定的限制性位点,或优化特定的密码子。Such framework sequences are available from public DNA databases containing germline antibody gene sequences. These germline sequences differ from mature antibody gene sequences by not fully including the assembled variable genes formed by V(D)J junctions during B cell maturation. Germline gene sequences also differ from those of high-affinity secondary antibodies in variable genes, typically centered in the CDRs. For example, somatic mutations are relatively rare in the amino-terminal portion of framework region 1 and the carboxy-terminal portion of framework region 4. Thus, it is not necessary to obtain the complete DNA sequence of a particular antibody to regenerate a complete recombinant antibody with a binding chemistry similar to that of the original antibody (see WO 99/45962). The heavy and light chain sequences partially spanning the CDR regions were used to determine germline variable and junctional gene segments involved in recombined antibody variable genes. The missing portions of the variable regions were then filled in with germline sequences. The heavy and light chain leader sequences are cleaved upon protein maturation and do not participate in the properties of the final antibody. To add missing sequences, cloned cDNA sequences were ligated with synthetic oligonucleotides by ligation or PCR amplification. Alternatively, complete variable regions can be synthesized as a set of short overlapping oligonucleotides and combined by PCR to generate complete synthetic variable region clones. This process has specific advantages, such as deletion or insertion of specific restriction sites, or optimization of specific codons.
来自杂交瘤的重链和轻链转录子的核苷酸序列可用于设计一组重叠的合成寡核苷酸而产生具有与天然序列相同的氨基酸编码能力的合成的V序列。合成的重链和κ链序列可在三个方面不同于天然序列:打 断重复核苷酸碱基的排列,以利于寡核苷酸合成和PCR扩增;根据Kozak的原则(Kozak,J.Biol.Chem.266,19867-19870(1991)引入优化的翻译起始位点;和在翻译起始位点上游构建HindIII位点。The nucleotide sequences of the heavy and light chain transcripts from the hybridomas can be used to design an overlapping set of synthetic oligonucleotides to generate a synthetic V sequence with the same amino acid encoding capacity as the native sequence. Synthetic heavy and kappa chain sequences can differ from natural sequences in three respects: the arrangement of repeated nucleotide bases is interrupted to facilitate oligonucleotide synthesis and PCR amplification; according to Kozak's principles (Kozak, J. Biol. Chem. 266, 19867-19870 (1991) introduction of an optimized translation initiation site; and construction of a HindIII site upstream of the translation initiation site.
对重链和轻链可变区而言,优化的编码和对应的非编码链序列在相应的非编码核苷酸寡核苷酸的中部打断为30-50个核苷酸。因此,对每条链而言,寡核苷酸可组装为重叠的双链形式,跨越150-400个核苷酸。然后以其作为模板,产生150-400个核苷酸的PCR扩增产物。典型地,单个可变区寡核苷酸组将打断为2组,分别扩增产生两个重叠的PCR产物。然后将这些重叠的产物通过PCR扩增连接,形成完整的可变区。在PCR扩增中也需要重链或轻链恒定区(包括κ轻链的BbsI位点,或γ重链的AgeI位点)的重叠片段,以产生可易于克隆到表达载体构建体中的片段。For the heavy and light chain variable regions, the optimized coding and corresponding noncoding strand sequences were interrupted by 30-50 nucleotides in the middle of the corresponding noncoding nucleotide oligonucleotides. Thus, oligonucleotides can assemble in overlapping double-stranded form, spanning 150-400 nucleotides per strand. Then use it as a template to generate a PCR amplification product of 150-400 nucleotides. Typically, a single variable region oligonucleotide set will be broken into 2 sets, amplified separately to generate two overlapping PCR products. These overlapping products are then joined by PCR amplification to form the complete variable region. Overlapping fragments of the heavy or light chain constant regions (including the BbsI site for the kappa light chain, or the AgeI site for the gamma heavy chain) are also required in PCR amplification to generate fragments that can be easily cloned into expression vector constructs .
然后将重新构建的重链和轻链可变区与克隆的启动子、引导序列、翻译起始区、恒定区3′非翻译区、多聚腺苷化和转录终止区、形成表达载体构建体的序列连接。重链和轻链表达构建体也可与单个载体共转染、顺序转染或单独转染到宿主细胞中,然后融合而从宿主细胞中表两条链。The reconstituted heavy and light chain variable regions were then combined with the cloned promoter, leader sequence, translation initiation region, constant region 3' untranslated region, polyadenylation and transcription termination region, to form an expression vector construct sequence connection. The heavy and light chain expression constructs can also be co-transfected with a single vector, sequentially transfected, or separately transfected into a host cell and then fused to express both chains from the host cell.
相似的流程可用于将新型抗原特异性移植到存在的成熟抗体中。典型地,受体抗体选自来源于相同的可变胚系基因作为CDR供体的抗体,但也可选择其它受体抗体。然后将供体抗体中的一个或单个CDRs通过上述技术进行转移。A similar procedure can be used to graft novel antigen specificity into existing mature antibodies. Typically, recipient antibodies are selected from antibodies derived from the same variable germline genes as the CDR donors, but other recipient antibodies may also be selected. One or individual CDRs in the donor antibody are then transferred by the techniques described above.
在本发明的一个技术方案中,-003和005和-024的结构特征用于产生结构相关的至少保留-003和005和-024的一个功能特性,即与CD3 8结合的抗CD38抗体,例如人抗CD3 8抗体。更具体地,可将-003和005和-024的一个或多个CDR区与已知的人框架区和CDRs连接,从而产生本发明的其它重组构建的人抗CD38抗体。In a technical solution of the present invention, the structural features of -003 and 005 and -024 are used to generate structurally related anti-CD38 antibodies that retain at least one functional property of -003, 005 and -024, that is, binding to CD38, for example Human anti-CD3 8 antibody. More specifically, one or more CDR regions of -003 and 005 and -024 can be linked to known human framework regions and CDRs to generate other recombinantly constructed human anti-CD38 antibodies of the invention.
用于构建人IgGκ的表达载体的示例质粒如下所述。构建质粒,使PCR扩增的Vκ重链和Vκ轻链cDNA序列用于重新构建完整的重链和轻链微基因。这些质粒可用于表达完整的人IgG1,κ或IgG4,κ抗体,类似的质粒可构建以表达其它重链同型体,或表达含λ轻链的抗体。Exemplary plasmids for constructing expression vectors for human IgGκ are as follows. Plasmids were constructed so that the PCR-amplified Vκ heavy chain and Vκ light chain cDNA sequences were used to reconstruct complete heavy and light chain minigenes. These plasmids can be used to express fully human IgG1, kappa or IgG4, kappa antibodies, and similar plasmids can be constructed to express other heavy chain isotypes, or to express antibodies containing lambda light chains.
本发明的CD38BPs,例如本发明的人抗CD38抗体可通过多种不同方式分离和鉴定,例如,可将筛选的杂交瘤在合适的烧瓶中培养以进行 单克隆抗体纯化。然后在用蛋白A-葡聚糖的亲和层析(对IgG1同型体抗体而言)(Pharmacia,Piscataway,NJ)或抗人IgG包被的葡聚糖,或对IgG3同型体抗体而言用蛋白G-葡聚糖进行亲和层析之前过滤上清,并进行浓缩。洗脱的IgG可通过凝胶电泳和高效液相色谱来检测以保证纯度。缓冲液可使用PBS,浓度可通过用1.43消光系数来测定OD280。等分单克隆抗体并在-80℃保存。The CD38BPs of the present invention, such as the human anti-CD38 antibodies of the present invention, can be isolated and identified in various ways, for example, the screened hybridomas can be cultured in a suitable flask for monoclonal antibody purification. This was followed by affinity chromatography with protein A-dextran (for IgG1 isotype antibodies) (Pharmacia, Piscataway, NJ) or anti-human IgG-coated dextran, or for IgG3 isotype antibodies with The supernatant was filtered and concentrated before protein G-glucan affinity chromatography. Eluted IgG can be checked by gel electrophoresis and high performance liquid chromatography to ensure purity. PBS can be used as the buffer, and the concentration can be determined by using an extinction coefficient of 1.43 to determine the OD 280 . Aliquot the monoclonal antibody and store at -80°C.
为了测定是否筛选的CD38BPs,例如人抗CD38单克隆抗体与特定的抗原决定簇结合,可使用定点或多点突变技术。To determine whether selected CD38BPs, such as human anti-CD38 monoclonal antibodies, bind to specific epitopes, site-directed or multiple point mutagenesis techniques can be used.
为了测定纯化抗体的同种型,可进行同种型ELISAs。微孔板的孔可用10μg/ml抗人Ig在4℃包被过夜。板用5%BSA(牛血清蛋白)封闭后,与10μg/ml单克隆抗体或纯化的同种型对照在室温下反应2个小时。然后将孔与人特异IgG1、IgG2、IgG3或IgG4、IgE、IgA1、IgA2或人IgM的偶联碱性磷酸酶的探针反应。洗涤后,用pNPP底物(1mg/ml)对板显色,并通过405nm处的OD进行分析。To determine the isotype of purified antibodies, isotype ELISAs can be performed. Wells of microplates can be coated with 10 μg/ml anti-human Ig overnight at 4°C. Plates were blocked with 5% BSA (bovine serum albumin) and reacted with 10 μg/ml monoclonal antibody or purified isotype control for 2 hours at room temperature. The wells were then reacted with alkaline phosphatase-conjugated probes specific for human IgG1, IgG2, IgG3 or IgG4, IgE, IgAl, IgA2 or human IgM. After washing, the plates were developed with pNPP substrate (1 mg/ml) and analyzed by OD at 405 nm.
可使用流式细胞仪来检测抗CD38抗体在免疫鼠的血清中的存在或CD38BPs(包括抗CD38抗体)与表达CD38的活细胞的结合。简言之,表达CD38的细胞系(在标准生长条件下生长)与各种浓度的溶在含0.1%BSA和0.02%叠氮化钠的PBS中的CD38BP混合,在4℃温育30分钟。洗涤后,将细胞与荧光素标记的抗人IgG抗体在与一抗染色相同的条件下进行反应。可用流式细胞仪(例如Becton Dickinson FACS仪)通过流式细胞仪对样品进行分析,以日光和侧向光散射特性来对单个活细胞设门。可使用通过荧光显微镜技术的方法(除外或替代)流式细胞仪方法。可如上所述对细胞进行染色,并通过荧光显微镜进行检测。该方法可观察单个细胞,但根据抗原密度可能降低灵敏度。Flow cytometry can be used to detect the presence of anti-CD38 antibodies in the sera of immunized mice or the binding of CD38BPs (including anti-CD38 antibodies) to live cells expressing CD38. Briefly, CD38-expressing cell lines (grown under standard growth conditions) were mixed with various concentrations of CD38BP in PBS containing 0.1% BSA and 0.02% sodium azide and incubated at 4°C for 30 minutes. After washing, cells were reacted with fluorescein-labeled anti-human IgG antibody under the same conditions as for primary antibody staining. Samples can be analyzed by flow cytometry using a flow cytometer (eg, a Becton Dickinson FACS instrument), gating on individual living cells on sunlight and side light scatter properties. Methods by fluorescence microscopy (in addition to or instead of) flow cytometric methods may be used. Cells can be stained as described above and examined by fluorescence microscopy. This method allows visualization of single cells, but sensitivity may be reduced depending on antigen density.
CD38BPs,例如CD38人IgGs可进一步通过Western印迹检测对CD38抗原的反应性。简言之,制备表达CD38细胞的细胞提取物,并进行十二烷基磺酸钠(SDS)聚丙烯酰胺凝胶电泳。电泳后,将分离的抗原转移到硝酸纤维素膜上,用20%脱脂奶粉封闭,并用待测的CD38BPs进行检测。可用抗人IgG碱性磷酸酶来检测人IgG的结合,用BCIP/NBT底物片(SigmaChem.Co.,St.Louis,MO)进行显色,但也可用CD38BP其它特异部分来直接检测。CD38BPs, such as CD38 human IgGs, can be further tested for reactivity to CD38 antigen by Western blotting. Briefly, cell extracts of CD38-expressing cells were prepared and subjected to sodium dodecylsulfate (SDS) polyacrylamide gel electrophoresis. After electrophoresis, the separated antigens were transferred to nitrocellulose membranes, blocked with 20% nonfat dry milk, and detected with the CD38BPs to be tested. Binding of human IgG can be detected with anti-human IgG alkaline phosphatase, developed with BCIP/NBT substrate sheets (SigmaChem. Co., St. Louis, MO), but can also be directly detected with other specific portions of CD38BP.
除了与CD38特异结合外,可检测CD38BPs(包括人抗CD38抗体) 对表达CD38的细胞的各种活性,例如,但不限定于胰岛素产生、Ca2+ 释放、细胞因子产生、裂解诱导作用、分化和增殖的抑制作用。In addition to specific binding to CD38, various activities of CD38BPs (including human anti-CD38 antibodies) on CD38-expressing cells can be detected, such as, but not limited to, insulin production, Ca 2+ release, cytokine production, lysis induction, differentiation and inhibition of proliferation.
在一个技术方案中,本发明提供可表达特异结合CD38的人抗体的转基因和转染色体非人动物,例如转基因或转染色体鼠。在一个特定技术方案中,本发明提供具有含人重链转基因的基因组的转基因或转染色体鼠,当用表达CD38的细胞免疫时,该鼠可产生人抗CD38抗体。在转基因情况下,人重链转基因可整合到鼠染色体DNA中,例如HuMAb鼠,如下详细描述。选择性地,在转染色体鼠(例如KM)情况下,人重链转基因可在染色体外维持,如WO02/43478所述。这种转基因和转染色体动物可通过V-D-J/V-J重组和同种型转换而产生多种针对CD38的人单克隆抗体的同种型(例如IgG、IgA和/或IgE)。对具有异源抗体库的外源抗原刺激应答的转基因或转染色体非人动物的设计需要转基因动物中所含的异源免疫球蛋白转基因在B细胞发育过程中正确行使功能。这包括,例如异源重链转基因的同种型转换。因此,构建转基因,使其可诱导同种型转换及具有一个或多个以下抗体基因的特征:(1)高水平和细胞类型特异的表达,(2)功能性基因重排,(3)激活并对等位基因排除有应答,(4)表达足够的一级库,(5)信号转导,(6)体细胞高突变,及(7)在免疫应答中转基因抗体座位是显性的。In one technical solution, the present invention provides transgenic and transchromosomal non-human animals expressing human antibodies that specifically bind to CD38, such as transgenic or transchromosomal mice. In a specific embodiment, the invention provides a transgenic or transchromosomal mouse having a genome comprising a human heavy chain transgene, which mouse produces human anti-CD38 antibodies when immunized with cells expressing CD38. In the transgenic case, the human heavy chain transgene can be integrated into the chromosomal DNA of a mouse, eg a HuMAb mouse, as described in detail below. Alternatively, in the case of transchromosomal mice (eg KM), the human heavy chain transgene can be maintained extrachromosomally, as described in WO02/43478. Such transgenic and transchromosomal animals can produce various isotypes (eg, IgG, IgA and/or IgE) of human monoclonal antibodies directed against CD38 by V-D-J/V-J recombination and isotype switching. The design of transgenic or transchromosomal non-human animals that respond to foreign antigen stimulation with a heterologous antibody repertoire requires that the heterologous immunoglobulin transgenes contained in the transgenic animals function correctly during B cell development. This includes, for example, isotype switching of heterologous heavy chain transgenes. Therefore, transgenes were constructed to induce isotype switching and to be characterized by one or more of the following antibody genes: (1) high-level and cell-type-specific expression, (2) functional gene rearrangement, (3) activation and respond to allelic exclusion, (4) express sufficient primary repertoire, (5) signal transduction, (6) somatic hypermutation, and (7) are dominant in the transgenic antibody locus in the immune response.
并不是所有前述标准都满足。例如,在某些技术方案中,其中转基因动物的内源免疫球蛋白座位是被功能上破坏的,转基因不需激活等位基因排除反应。另外,在某些技术方案中,其中转基因含功能性重组的重链和/或轻链免疫球蛋白基因,因此功能性基因重组的第二个标准是不需要的,至少对转基因已经重组的情况而言。对于分子免疫学背景,参见,Fundamental Immunology,2nd edition(1989)、Paul William E.,ed.Raven Press,N.Y。Not all of the foregoing criteria are met. For example, in certain embodiments in which the endogenous immunoglobulin loci of the transgenic animal are functionally disrupted, the transgene need not activate an allelic exclusion response. In addition, in certain technical solutions, where the transgene contains functionally recombined heavy and/or light chain immunoglobulin genes, the second criterion of functional genetic recombination is not required, at least for cases where the transgene has been recombined In terms of.

在特定技术方案中,转基因或转染色体非人动物用于在转基因动物的胚系中产生含重组的、未重组的或同时含有重组和未重组的异源免疫球蛋白重链和轻链转基因的本发明的人单克隆抗体。每种重链转基因含有至少一个CH基因。另外,重链转基因可含有功能性同型体转换序列,可支持在转基因动物的B细胞中编码多个CH基因的异源转基因的同种型转换。这种转换序列是那些在作为转基因CH基因来源的物种中的胚系免疫球蛋白座位中天然存在的序列,或这种转换序列来源于那些在接 受转基因构建体的物种(转基因动物)中存在的序列。例如,用于产生转基因鼠的人转基因构建体如果整合了那些与鼠重链座位天然存在的序列相似的转换序列,则可产生高频率的同种型转换事件,可能鼠转换序列优先对鼠转换重组酶系统起作用,而人转换序列不是这样。可通过常规克隆方法分离和克隆转换序列,或从基于免疫球蛋白转换区序列相关的公布的序列信息设计的重叠的合成寡核苷酸从头合成(Mills et al.,Nucl.Acids Res.15,7305-7316(1991)Sideras et al.,Intl.Immunol.1,631-642(1989))。对每种前述转基因动物而言,在转基因动物的B细胞中发现大部分有功能的重组异源重链和轻链免疫球蛋白转基因(至少10%)。In a specific technical solution, a transgenic or transchromosomal non-human animal is used to produce recombinant, unrecombined, or both recombinant and unrecombined heterologous immunoglobulin heavy and light chain transgenes in the germline of the transgenic animal. Human monoclonal antibodies of the invention. Each heavy chain transgene contains at least one CH gene. In addition, the heavy chain transgene can contain a functional isotype switching sequence that can support isotype switching of heterologous transgenes encoding multiple CH genes in the B cells of the transgenic animal. Such switch sequences are those found naturally at germline immunoglobulin loci in the species from which the transgenic CH gene was derived, or such switch sequences are derived from those present in the species receiving the transgenic construct (transgenic animal) the sequence of. For example, human transgene constructs used to generate transgenic mice that incorporate switch sequences that are similar to those naturally occurring at the murine heavy chain locus can generate high frequencies of isotype switching events, presumably the murine switch sequences preferentially switch to the murine The recombinase system works whereas the human switch sequence does not. The switch sequence can be isolated and cloned by conventional cloning methods, or synthesized de novo from overlapping synthetic oligonucleotides designed based on published sequence information related to immunoglobulin switch region sequences (Mills et al., Nucl. Acids Res. 15, 7305-7316 (1991) Sideras et al., Intl. Immunol. 1, 631-642 (1989)). For each of the aforementioned transgenic animals, the majority of functional recombinant heterologous heavy and light chain immunoglobulin transgenes (at least 10%) were found in the B cells of the transgenic animals.
用于产生本发明的转基因非人动物的转基因包括含编码至少一个可变基因片段、一个多样性基因片段、一个连接基因片段和至少一个恒定区基因片段的DNA的重链转基因。免疫球蛋白轻链转基因含有编码至少一个可变基因片段、一个连接基因片段和至少一个恒定区基因片段的DNA。编码轻链和重链基因片段的基因片段对转基因动物是异源的,因为它们来源于或对应于编码来自不组成转基因非人动物的物种的免疫球蛋白重链和轻链基因片段的DNA。在本发明的一个技术方案中,构建转基因,使单个基因片段不重组,即不重排以编码功能性免疫球蛋白轻链或重链。这种未重排的转基因可支持V、D和J基因片段的重组(功能性重组),而且支持当暴露到CD38抗原中,所有或部分D区整合在转基因动物中所得到的重组免疫球蛋白重链中。The transgenes used to generate the transgenic non-human animals of the invention include heavy chain transgenes comprising DNA encoding at least one variable gene segment, one diversity gene segment, one junction gene segment, and at least one constant region gene segment. The immunoglobulin light chain transgene contains DNA encoding at least one variable gene segment, one junction gene segment and at least one constant region gene segment. The gene segments encoding the light and heavy chain gene segments are heterologous to the transgenic animal in that they are derived from or correspond to DNA encoding the immunoglobulin heavy and light chain gene segments from the species that does not make up the transgenic non-human animal. In one technical solution of the present invention, the transgene is constructed so that a single gene segment does not recombine, that is, does not rearrange to encode a functional immunoglobulin light chain or heavy chain. This unrearranged transgene supports recombination of the V, D, and J gene segments (functional recombination) and supports the resulting recombinant immunoglobulin in the transgenic animal when all or part of the D region is integrated when exposed to the CD38 antigen in the heavy chain.
在选择的技术方案中,转基因含有未重组的“微座位”。这种转基因典型地含有C、D和J片段的实质部分,及V基因片段的亚组。在这种转基因构建体中,各种调控序列,例如启动子、增强子、种类转换区、RNA加工中的拼接供体和拼接受体序列、重组信号等均含有来自异源DNA的相应序列。这种调控序列可整合到来自本发明所用的非人动物相同或相关的物种中的转基因中。例如,人免疫球蛋白基因片段可与转基因中用于转基因鼠的啮齿类免疫球蛋白增强子序列连接。选择性地,合成的调控序列可整合在转基因中,其中这种合成的调控序列不与已知天然存在于哺乳动物基因组中的功能DNA序列同源。合成的调控序列根据同一性原则进行设计,例如,那些特异针对拼接受体位点或启动子/增强子元件的允许序列。例如,与天然存在的胚系Ig座位相比较,微座 位含有至少一个内部(即不在部分的末端)缺失非必需DNA部分(例如,干扰序列;内含子或其内含子或部分)的基因组免疫球蛋白座位。In a selected technical solution, the transgene contains unrecombined "microlocus". Such transgenes typically contain substantial portions of the C, D and J segments, and a subset of the V gene segments. In such transgenic constructs, various regulatory sequences, such as promoters, enhancers, species switching regions, splice donor and splice acceptor sequences in RNA processing, recombination signals, etc., all contain corresponding sequences from heterologous DNA. Such regulatory sequences may be incorporated into a transgene from the same or a related species of the non-human animal used in the invention. For example, a human immunoglobulin gene segment can be linked to a rodent immunoglobulin enhancer sequence in a transgene for a transgenic mouse. Alternatively, synthetic regulatory sequences may be incorporated into the transgene, where such synthetic regulatory sequences are not homologous to functional DNA sequences known to occur naturally in mammalian genomes. Synthetic regulatory sequences are designed on the basis of identity principles, for example, permissive sequences that are specific for splicing acceptor sites or promoter/enhancer elements. For example, a microlocus contains at least one genome in which nonessential DNA portions (e.g., interfering sequences; introns or introns or portions thereof) are deleted internally (i.e., not at the end of the portion) compared to naturally occurring germline Ig loci Immunoglobulin loci.
转基因和转染色体非人动物例如鼠的实施例具有显著的免疫球蛋白产生的库,理想地,在调整体积后与人的库实质上相似。Examples of transgenic and transchromosomal non-human animals such as murines have remarkably immunoglobulin-producing repertoires, ideally substantially similar to human repertoires after adjusting for volume.
在调整体积后,人的库理想地通常密度至少约为10%或更高,例如25%到50%或更多。通常,构建引入到鼠基因组中的V、J和D区的不同数目及V(-D-)J基因片段重组的其它多样性和连接区的随机核苷酸增加,可产生至少约1000个不同的免疫球蛋白(理想地为IgG1),例如104到106或更多。典型地,免疫球蛋白对预选的抗原的亲和性低于10-8M,例如低于10-9M、10-10 M或10-11M,或甚至更低。如上所述的转基因和转染色体非人动物,例如鼠可用例如表达Cd38的细胞免疫。选择性地,转基因动物可用编码人CD38的DNA免疫。然后动物产生B细胞,并通过转换重组(顺式转换)进行种类转换,并表达与CD38反应的免疫球蛋白。免疫球蛋白是人抗体(也称为“人序列抗体”),其中重链和轻链多肽由包括体细胞突变衍生的序列和V区重组连接序列及胚系编码序列的人转基因序列编码;这些人抗体是指实质上与人VL 和JL或VH、DH和JH基因片段编码的多肽序列相同,即使由于体细胞突变和不同的V-J和V-D-J重组连接而存在其它非胚系序列。每个抗体链的可变区典型地与胚系V和J基因片段同源性为80%,对重链而言,人胚系V、D和J基因片段通常与转基因中存在的人胚系序列的同源性至少为85%;通常90或95%或更高。但由于非胚系序列通过体细胞突变和VJ和VDJ连接而被引入,因此人序列抗体通常具有某些不被在鼠的胚系中的人转基因中的人V、D或J基因片段所编码的某些可变区序列。典型地,这种非胚系序列(或单个核苷酸位置)将成簇存在并邻近CDRs,或在簇中的体细胞突变是已知的区域。After volume adjustment, the human pool desirably typically has a density of at least about 10% or higher, such as 25% to 50% or more. Typically, different numbers of V, J, and D regions introduced into the murine genome by construction and other diversity in recombination of V(-D-)J gene segments and random nucleotide additions in junctional regions can produce at least about 1000 different of immunoglobulin (ideally IgG1), such as 10 4 to 10 6 or more. Typically, the immunoglobulin has an affinity for the preselected antigen of less than 10 −8 M, such as less than 10 −9 M, 10 −10 M or 10 −11 M, or even lower. Transgenic and transchromosomal non-human animals such as mice, as described above, can be immunized, for example, with cells expressing Cd38. Alternatively, transgenic animals can be immunized with DNA encoding human CD38. The animal then generates B cells that undergo class switching through switch recombination (cis-switching) and express immunoglobulins reactive with CD38. Immunoglobulins are human antibodies (also referred to as "human sequence antibodies") in which the heavy and light chain polypeptides are encoded by human transgenic sequences including sequences derived from somatic mutations and recombined junctional V region and germline coding sequences; these Human antibodies refer to polypeptide sequences substantially identical to human VL and JL or VH , DH , and JH gene segments encoded by human antibodies, even if other non-germline sequences are present due to somatic mutations and different VJ and VDJ recombination linkages. The variable regions of each antibody chain are typically 80% homologous to germline V and J gene segments, and for the heavy chains, human germline V, D, and J gene segments are usually identical to the human germline gene segments present in the transgene. The sequence identity is at least 85%; usually 90 or 95% or more. However, because non-germline sequences are introduced by somatic mutation and VJ and VDJ joining, human sequence antibodies usually have certain human V, D, or J gene segments not encoded by human transgenes in the germline of the mouse certain variable region sequences. Typically, such non-germline sequences (or single nucleotide positions) will be present in clusters adjacent to CDRs, or in regions where somatic mutations in clusters are known.
本发明也提供来源于此处所述的转基因或转染色体非人动物的B细胞。B细胞可用于产生表达与人CD38以高亲和性(例如,解离平衡常数(KD)低于10-8M)结合的人单克隆抗体的杂交瘤。因此,在一个技术方案中,本发明提供产生亲和性(KD)低于10-8M,例如低于10-9M、10-10M或10-11M,或甚至更低的人抗体,用放射性标记的单克隆抗体通过斯卡查德分析或通过FACS分析测定最大半衰期结合浓度、或通过表面等离子共振分析在BIAcore仪器上进行测定。本发明提供含由 以下组成的抗CD38抗体,其中人序列轻链含有(1)具有实质上与由人VL基因片段和人JL片段编码的多肽序列相同的多肽序列的轻链可变区,及(2)由人CL基因片段编码的轻链恒定区;人序列重链含有(1)具有实质上与由人VH基因片段、D区和人JH片段编码的多肽序列相同的多肽序列的轻链可变区,及(2)由人CH基因片段编码的轻链恒定区。应注意人D基因实质上通过重组和体细胞突变事件而发生改变,从而可能不易于识别原来的人胚系序列。The invention also provides B cells derived from the transgenic or transchromosomal non-human animals described herein. B cells can be used to generate hybridomas expressing human monoclonal antibodies that bind to human CD38 with high affinity (eg, dissociation equilibrium constant ( KD ) below 10 −8 M). Thus, in one embodiment, the present invention provides for the generation of human compounds having an affinity (K D ) below 10 −8 M, such as below 10 −9 M, 10 −10 M or 10 −11 M, or even lower. Antibodies, maximal half-life binding concentrations were determined by Scatchard analysis or by FACS analysis with radiolabeled monoclonal antibodies, or by surface plasmon resonance analysis on a BIAcore instrument. The present invention provides an anti-CD38 antibody comprising a human sequence light chain comprising (1) a light chain variable region having a polypeptide sequence substantially identical to a polypeptide sequence encoded by a human VL gene segment and a human JL segment , and (2) the light chain constant region encoded by the human CL gene segment; the human sequence heavy chain contains (1) a polypeptide sequence substantially identical to the polypeptide sequence encoded by the human VH gene segment, the D region and the human JH segment The light chain variable region of the polypeptide sequence, and (2) the light chain constant region encoded by the human CH gene fragment. It should be noted that the human D gene is substantially altered by recombination and somatic mutation events, so that the original human germline sequence may not be readily recognizable.
针对CD38的高亲和性人单克隆抗体的开发可通过扩展具有含整合的人免疫球蛋白转基因的基因组的转基因非人动物中的人可变区基因片段的文库的方法来进行,所述方法包括,将含不存在于所述整合的人免疫球蛋白转基因中的V区基因片段的V基因转基因整合到基因组中。通常,V区转基因是含有部分在人基因组中天然存在或通过重组方法拼接在一起的人VH或VL(Vκ)基因片段阵列的酵母人工染色体(YAC),这些片段包括无序的或省略的V基因片段。通常至少在YAC中含5个或更多功能性V基因片段。在这种变化中,可通过V文库扩展方法制备转基因动物,其中动物表达含有由存在于V区转基因上的V区基因片段编码的可变区序列和人Ig转基因上编码的C区的免疫球蛋白链。通过V文库扩展方法,可产生具有至少5个不同V基因的转基因动物;例如含至少约34个V基因或更多的动物。某些V基因片段可能是没有功能的(例如,假基因等);如果需要,这些片段可通过技术人员已知的重组方法被保留或选择性删除。Development of high-affinity human monoclonal antibodies directed against CD38 can be performed by a method of expanding libraries of human variable region gene fragments in transgenic non-human animals having genomes containing integrated human immunoglobulin transgenes Including, integrating into the genome a V gene transgene containing a V region gene segment not present in the integrated human immunoglobulin transgene. Typically, the V region transgene is a yeast artificial chromosome (YAC) containing an array of human VH or VL (Vκ) gene segments, including disordered or omitted The V gene fragment. Usually at least five or more functional V gene segments are contained in the YAC. In this variation, transgenic animals can be prepared by the V library expansion method, wherein the animal expresses an immunoglobulin containing the variable region sequences encoded by the V region gene segment present on the V region transgene and the C region encoded on the human Ig transgene protein chain. Through the V library expansion method, transgenic animals can be generated with at least 5 different V genes; for example, animals containing at least about 34 V genes or more. Certain V gene segments may be non-functional (eg, pseudogenes, etc.); if desired, these segments can be retained or selectively deleted by recombination methods known to the skilled artisan.
当构建含具有扩展的V片段文库的功能性YAC的鼠胚系,实质上不存在含J和C基因片段的人Ig转基因时,则可扩增该特性,并扩增到其它遗传背景,包括其中具有扩展的V片段文库的功能性YAC导入到具有不同的人Ig转基因的非人动物胚系的背景。多个具有扩展的V片段文库的功能性YACs可导入到胚系中,使其与人Ig转基因(或多个人Ig转基因)一起起作用。虽然此处是指YAC转基因,但如果这种转基因整合到实质上缺失酵母序列的基因组中时,例如在酵母中需自主复制序列中;则这种序列在酵母复制后不再需要时(即,在导入到鼠ES细胞或鼠原接合子(prozygote)中之前),可选择性地通过基因工程(例如,限制性消化和脉冲凝胶电泳或其它合适的方法)除去。扩增人序列免疫球蛋白表达的方法包括培养具有人Ig转基因,选择性地也具有含 扩展的V片段文库的功能性YAC的转基因动物。VH和VL基因片段均可存在于YAC中。转基因动物可在任何实验人员所需的背景中培养,包括含有其它人转基因,包括人Ig转基因和/或编码其它人淋巴细胞蛋白的转基因的背景。本发明也提供由具有扩展的V区文库YAC转基因产生的高亲和性人序列免疫球蛋白。虽然以上描述了本发明的转基因动物的特定技术方案,其它划分在以下3类中的技术方案是期望的:This property can be amplified when a murine germline containing a functional YAC with an expanded V segment library is constructed in the substantial absence of human Ig transgenes containing J and C gene segments, and extended to other genetic backgrounds, including Background in which a functional YAC with an expanded V-segment library was introduced into the germline of a non-human animal with a different human Ig transgene. Multiple functional YACs with an expanded V-segment library can be introduced into the germline to function with a human Ig transgene (or multiple human Ig transgenes). Although a YAC transgene is referred to here, if such a transgene is integrated into a genome that is substantially devoid of yeast sequences, such as in yeast where autonomously replicating sequences are required; then such sequences are no longer required after yeast replication (i.e., prior to introduction into murine ES cells or murine prozygotes) can optionally be removed by genetic engineering (eg, restriction digestion and pulsed gel electrophoresis or other suitable methods). Methods of amplifying expression of human sequence immunoglobulins include culturing transgenic animals with human Ig transgenes, optionally also functional YACs containing expanded V-segment libraries. Both VH and VL gene segments can be present in a YAC. Transgenic animals can be raised in any background desired by the experimenter, including backgrounds containing other human transgenes, including human Ig transgenes and/or transgenes encoding other human lymphocyte proteins. The invention also provides high affinity human sequence immunoglobulins produced from YAC transgenes with expanded V region libraries.

For example, CD38BPs can be used to elicit one or more of the following biological activities in vivo or in vitro: inhibition of CD38 function (e.g., enzymatic activity, signal transduction, induction of cytokine expression, induction of proliferation or differentiation, and/or induction of lysis), killing of expressed CD38-expressing cells, mediate phagocytosis or ADCC of CD38-expressing cells in the presence of human effector cells, and mediate CDC of CD38-expressing cells in the presence of complement, or kill CD38-expressing cells by apoptosis.
在存在补体时,也可使用任何含具有补体结合位点,例如结合补体的来源于IgG1、-2或-3或IgM的一部分的本发明的CD38BPs的组分。在一个技术方案中,离体治疗含具有本发明的CD38BP的靶细胞和合适的效应细胞的细胞群可通过加入补体或含补体的血清而进行补充。被本发明的CD38BP包被的靶细胞的吞噬作用或裂解可通过补体蛋白的结合而增强。在一个技术方案中,包被本发明的CD38BPs的靶细胞也可被补体裂解。在一个技术方案中,本发明的CD38BPs不激活补体。In the presence of complement, any composition comprising CD38BPs of the invention having a complement binding site, eg, a portion derived from IgGl, -2 or -3 or IgM, that binds complement may also be used. In one embodiment, ex vivo treatment of a population of cells comprising target cells bearing a CD38BP of the invention and suitable effector cells may be supplemented by addition of complement or complement-containing serum. Phagocytosis or lysis of target cells coated with CD38BP of the present invention can be enhanced by binding of complement proteins. In one technical solution, target cells coated with CD38BPs of the present invention can also be lysed by complement. In one technical solution, the CD38BPs of the present invention do not activate complement.
本发明的CD38BPs也可与补体一起给药。因此,含血清或补体的CD38BPs也在本发明的范围中。在这些组分中,补体通过例如偶联而紧邻CD38BPs,或适于进行同时给药。选择性地,CD38BPs和补体或血清可单独给药。The CD38BPs of the invention can also be administered with complement. Therefore, CD38BPs containing serum or complement are also within the scope of the present invention. In these components, complement is in close proximity to CD38BPs, eg by conjugation, or is suitable for simultaneous administration. Alternatively, CD38BPs and complement or serum can be administered alone.
本发明的CD38BPs也用于针对表达FcγR或CD38的细胞,例如用于标记这类细胞。对这种用途而言,CD38BP可与能被检测的分子连接。因此,本发明提供离体或在体外定位表达Fc受体,例如FcγR或CD38的细胞的方法。可检测标记可以是例如放射性同位素、荧光化合物、酶或酶辅因子。CD38BPs of the invention are also useful for targeting cells expressing FcyR or CD38, for example for labeling such cells. For this use, CD38BP can be linked to a molecule that can be detected. Accordingly, the present invention provides methods for localizing ex vivo or in vitro cells expressing Fc receptors, such as FcyR or CD38. A detectable label can be, for example, a radioisotope, a fluorescent compound, an enzyme or an enzyme cofactor.
靶特异的效应细胞,例如与本发明的CD38BP连接的效应细胞也可用作治疗性试剂。定位的效应细胞可以是人淋巴细胞,例如巨噬细胞、嗜中性粒细胞或单核细胞。其它细胞包括嗜曙红细胞、自然杀伤细胞和其它含IgG或IgA受体的细胞。如果需要,效应细胞可从被治疗的患者中获得。靶特异的效应细胞可在生理上可接受的溶液中作为悬浮液进行给药。给药的细胞数目可在108到109,但可根据治疗目的而改变。通常使用可在靶细胞,例如表达CD38的肿瘤细胞获得定位,并通过例如吞噬作用或裂解而有效杀死细胞的足够的量。Target-specific effector cells, eg, effector cells linked to a CD38BP of the invention may also be used as therapeutic agents. The targeted effector cells may be human lymphocytes such as macrophages, neutrophils or monocytes. Other cells include eosinophils, natural killer cells, and other IgG or IgA receptor-containing cells. Effector cells can be obtained from the patient being treated, if desired. Target-specific effector cells can be administered as a suspension in a physiologically acceptable solution. The number of cells administered can range from 10 8 to 10 9 , but can vary depending on the therapeutic purpose. Sufficient amounts are generally used to achieve localization in target cells, eg, CD38-expressing tumor cells, and to effectively kill the cells, eg, by phagocytosis or lysis.
用靶特异的效应细胞的治疗可联合其它清楚靶细胞的技术来进行。例如,使用本发明的CD38BPs和/或针对这些组分的效应细胞的抗肿瘤治疗可与化疗联合使用。另外,联合免疫治疗可用于指导两种不同的细胞毒素效应物群针对肿瘤细胞抑制。例如与抗FcγRI或抗CD3连接的CD38BP可与IgG或IgA受体特异结合试剂联合使用。本发明的双特异性和多特异性分子也可用于例如通过在细胞表面加帽和删除受体来调控效应细胞上的FcαR或FcγR水平。抗Fc受体的混合物也可用于该目的。Therapy with target-specific effector cells can be performed in conjunction with other techniques for elucidating target cells. For example, antitumor therapy using CD38BPs of the invention and/or effector cells directed against these components can be used in combination with chemotherapy. Additionally, combination immunotherapy can be used to direct two distinct cytotoxic effector populations against tumor cell suppression. For example, CD38BP linked to anti-FcyRI or anti-CD3 can be used in combination with IgG or IgA receptor specific binding reagents. Bispecific and multispecific molecules of the invention can also be used to modulate FcαR or FcγR levels on effector cells, eg, by capping and deleting receptors on the cell surface. Cocktails of anti-Fc receptors can also be used for this purpose.

Complex formation is then detected, wherein a difference in complex formation between samples compared to a control sample indicates the presence of CD38 antigen in the sample. Examples of detection immunoassay methods include, but are not limited to, ELISA, RIA, FACS detection, plasmon resonance detection, chromatographic detection, tissue immunohistochemistry, Western blotting, and/or immunoprecipitation.
在一个技术方案中,本发明的CD38BPs可用于检测CD38的循环水平或在其膜表面含CD38的细胞水平,然后将该水平与特定的疾病症状相关联。选择性地,CD38BPs可用于清除或与表达CD38的细胞相互作用,从而表明这些细胞是疾病的重要介导物。也可通过将样品和对照样品与抗CD38抗体在适于在抗体和CD38形成复合物的条件下接触。检测抗体和CD38形成的任何复合物,并将样品和对照进行比较。本发明的CD38BPs最初可在体外检测治疗和诊断用途相关的结合活性。例如,可用流式细胞仪检测CD38BPs。另外,可检测CD38BPs在引发至少一种效应细胞介导的效应细胞活性方面的活性。例如,可检测本发明 的抗CD38抗体引发CDC和/或凋亡的能力。检测CDC、同型黏附、分子成簇或凋亡的流程在本领域是已知的。In one technical solution, the CD38BPs of the present invention can be used to detect the circulating level of CD38 or the level of cells containing CD38 on their membrane surface, and then correlate the level with a specific disease symptom. Alternatively, CD38BPs can be used to clear or interact with CD38-expressing cells, thereby suggesting that these cells are important mediators of disease. It can also be achieved by contacting the sample and control samples with an anti-CD38 antibody under conditions suitable for complex formation of the antibody and CD38. Any complexes formed by the antibody and CD38 were detected and samples were compared to controls. The CD38BPs of the present invention can initially be tested in vitro for binding activity relevant to therapeutic and diagnostic uses. For example, CD38BPs can be detected by flow cytometry. Additionally, the activity of CD38BPs in eliciting at least one effector cell-mediated effector cell activity can be detected. For example, anti-CD38 antibodies of the invention can be tested for their ability to elicit CDC and/or apoptosis. Protocols for detecting CDC, homotypic adhesion, molecular clustering or apoptosis are known in the art.

A therapeutically effective amount of CD38BP can vary depending on factors such as the disease state, age, sex and weight of the individual, and the CD38BP eliciting the desired response in the individual. A therapeutically effective amount is also one in which any toxic or detrimental effects of the antibody or antibody portion outweigh the therapeutically beneficial effects. A "prophylactically effective amount" means an amount that achieves the desired prophylactic result (e.g., reduces the likelihood of developing disease, reduces the intensity and spread of disease, increases the likelihood of survival when disease is imminent, delays symptoms of disease) for the time needed. seizures, etc.) effective dose. Typically, prophylactically effective doses will be lower than therapeutically effective doses since prophylactic doses are administered to patients prior to the early stages of the disease. A "therapeutically effective amount" for tumor treatment can also be determined by its ability to stabilize disease progression. The ability of a compound to inhibit cancer can be evaluated in animal model systems for its effectiveness in human tumors. Alternatively, this property of a component can be assessed for the ability of the compound to inhibit cell growth or induce apoptosis by in vitro assays known to the skilled artisan. A therapeutically effective amount of a therapeutic compound reduces tumor volume or alleviates symptoms in a patient. The dosage can be determined by one skilled in the art based on factors such as the patient's weight, the severity of the patient's condition and the particular compound or route of administration chosen.
风湿性关节炎的“治疗有效量”可在患者中产生至少ACR20初步疗效判定标准,例如至少ACR50初步疗效判定标准,例如至少ARC70初步疗效判定标准。ACR20初步疗效判定标准定义为:在压痛关节计数 (TJC)提高≥20%,并在以下5项评估中提高≥20%:患者疼痛评估(VAS)1、患者整体评估(VAS)、医生整体评估(VAS)、患者自测无力(HAQ)急性阶段反应物(CRP或ESR)。ACR50和ACR70以相同方式定义为分别≥50%和≥70%的提高。对于进一步的细节,参见Felsonet al.,in American College of Rheumatology PreliminaryDefinition ofImprovement in Rheumatoid Arthriffs;Arthritis Rheumatism 38,727-735(1995)。A "therapeutically effective amount" for rheumatoid arthritis produces at least an ACR 20 preliminary response criterion, eg, at least an ACR 50 preliminary response criterion, eg, at least an ARC 70 preliminary response criterion, in the patient. ACR 20 preliminary efficacy criteria are defined as: ≥ 20% improvement in tender joint count (TJC), and ≥ 20% improvement in the following 5 assessments: Patient Pain Assessment (VAS)1, Patient Overall Assessment (VAS), Physician Overall Assessment assessment (VAS), patient self-assessment of weakness (HAQ), acute phase reactants (CRP or ESR). ACR 50 and ACR 70 were defined in the same way as improvements of >50% and >70%, respectively. For further details see Felson et al., in American College of Rheumatology Preliminary Definition of Improvement in Rheumatoid Arthriffs; Arthritis Rheumatism 38, 727-735 (1995).
选择性地,风湿性关节炎的治疗有效量可通过由EULAR定义的DAS(疾病活动度评分),包括DAS28和/或DAS56来测定。Alternatively, the therapeutically effective amount for rheumatoid arthritis can be determined by DAS (Disease Activity Score) defined by EULAR, including DAS28 and/or DAS56.
调整剂量以提供最适的所需应答(例如,治疗性应答)。例如,可进行单点注射给药,也可随时间进行几次分开的剂量给药,或根据治疗情况的紧急性按比例减小或增加剂量。肠胃外组分可配制成易于给药的剂量单位和通用剂量形式。此处所用剂量单位形式是指适于被治疗患者的个别的适于作为单一剂量的形式;每个单位含预定量的活性化合物以在与所需药物载体联合时产生所需的治疗效果。本发明的剂量单位形式的规格由和直接依赖于(a)活性化合物的特定性质和需达到的特定治疗效果,及(b)配制方面本身的限制,例如用于治疗的活性化合物在个体中的灵敏度而确定。本发明的CD38BPs的有效剂量和剂量形式根据被治疗疾病或症状而由本领域技术人员来确定。本发明的化合物的治疗有效剂量的示例的非限制性范围是约0.1-100mg/kg、譬如约0.1-50mg/kg、例如约0.1-20mg/kg、譬如约0.1-10mg/kg、例如约0.5、譬如约0.3、约1或约3mg/kg。Dosage is adjusted to provide the optimum desired response (eg, a therapeutic response). For example, administered as a single injection, several divided doses may be administered over time or the dose may be proportionally reduced or increased as indicated by the exigencies of the therapeutic situation. Parenteral compositions can be formulated in dosage units and general dosage forms for ease of administration. Dosage unit form as used herein refers to individual forms suited as unitary dosages for the subject to be treated; each unit containing a predetermined quantity of active compound to produce the desired therapeutic effect in association with the required pharmaceutical carrier. The specifications for the dosage unit forms of the invention consist of and are directly dependent on (a) the particular properties of the active compound and the particular therapeutic effect to be achieved, and (b) limitations inherent in formulation, such as the amount of active compound used for treatment in an individual.

Examples of suitable enzymes include horseradish peroxidase, alkaline phosphatase β-galactosidase, or acetylcholinesterase; examples of suitable prosthetic group complexes include streptavidin/biotin and avidin/ Biotin; examples of suitable fluorescent materials include umbelliferone, fluorescein, fluorescein isothiocyanate, rhodamine, dichlorotriazinylamine, fluorescein, dansyl chloride, or phycoerythrin; chemiluminescent materials Examples of suitable radioactive materials include luminol; examples of suitable radioactive materials include 125 I, 131 I, 35 S, and 3 H.
也可在生物样品中通过竞争免疫检测法,用标记可检测底物的CD38肽标准品和未标记的CD38BP,例如未标记的抗CD38抗体来检测CD38BPs。在这种检测中,生物样品、标记的CD38肽标准品和CD38BP结合,从而测定与未标记CD38BP结合的标记的CD38标准品的量。生物样品中的CD38肽的量与结合到CD38BP上的标记的CD38标准品的量成反比。CD38BPs can also be detected in biological samples by competition immunoassays using a CD38 peptide standard labeled with a detectable substrate and unlabeled CD38BP, eg, an unlabeled anti-CD38 antibody. In this assay, a biological sample, a labeled CD38 peptide standard, and CD38BP are combined to determine the amount of labeled CD38 standard bound to unlabeled CD38BP. The amount of CD38 peptide in the biological sample is inversely proportional to the amount of labeled CD38 standard bound to CD38BP.
CD38BPs在体内肿瘤成像中是特别有用的。与CD38相关的体内成像可通过任何合适技术进行。例如在肿瘤中使用Tc-标记或用其它释放γ射线的同位素标记抗CD38抗体或次级标记(例如FITC标记)来自肿瘤的CD38BP:CD38复合物,并用γ闪烁照相机(例如Elscint Apex409ECT设备)进行成像,典型地使用低能、高分辨率瞄准仪或低能全目标瞄准仪。然后评估染色组织的放射性计数,作为肿瘤中CD38相关肽的量的指示。通过这种技术获得的图像可用于评估CD38在患者、哺乳动物或组织中的生物分布,例如,以CD38或CD38片段作为存在入侵的癌细胞的生物标志物。这种技术的改变可包括使用磁共振成像(MRI)改善通γ照相机的成像技术。类似的免疫成像方法和原理在例如Srivastava(ed.),Radiolabeled Monoclonal Antibodies For Imaging AndTherapy(Plenum Press 1988),Chase,″Medical Applications ofRadioisotopes,″in Remington′s PharmaceuticalSciences,18th Edition,Gennaro et al.,(eds.)、pp.624-652(Mack Publishing Co.,1990),andBrown,″Clinical Use of Monoclonal Antibodies,″in BiotechnologyAndPharmacy 227-49,Pezzuto et al.,(eds.)(Chapman&Hall 1993)中描述。这种图像也可用于其它抗癌试剂的定向递送,其实施例如此处所述 (例如,凋亡试剂、毒素或CHOP化疗组合物)。另外,这种图像也可或选择性地作为外科技术切除肿瘤的依据。另外,这种体内成像技术也可在具有肿瘤的患者中鉴定和定位肿瘤(由于存在其它生物标志物、转移等),但肿瘤不能通过传统分析技术鉴定。所有这些方法均是本发明的特征。CD38BPs are particularly useful in in vivo tumor imaging. In vivo imaging associated with CD38 can be performed by any suitable technique. For example in tumors use Tc-label or label anti-CD38 antibodies with other gamma-releasing isotopes or secondary label (eg FITC label) CD38BP:CD38 complexes from tumors and image with gamma scintillation camera (eg Elscint Apex409ECT device) , typically using a low-energy, high-resolution collimator or a low-energy all-target collimator. Radioactive counts of the stained tissue were then assessed as an indication of the amount of CD38-related peptide in the tumor. Images obtained by this technique can be used to assess the biodistribution of CD38 in patients, mammals or tissues, for example, using CD38 or CD38 fragments as a biomarker for the presence of invasive cancer cells. Variations of this technique may include the use of Magnetic Resonance Imaging (MRI) to improve imaging techniques with gamma cameras. Similar immunoimaging methods and principles are described, for example, in Srivastava (ed.), Radiolabeled Monoclonal Antibodies For Imaging And Therapy (Plenum Press 1988), Chase, "Medical Applications of Radioisotopes," in Remington's Pharmaceutical Sciences, 18th Edition, Gennaro et al., ( eds.), pp.624-652 (Mack Publishing Co., 1990), and Brown, "Clinical Use of Monoclonal Antibodies," in Biotechnology And Pharmacy 227-49, Pezzuto et al., (eds.) (Chapman & Hall 1993). Such images can also be used for targeted delivery of other anti-cancer agents, examples of which are described herein (e.g., apoptotic agents, toxins, or CHOP chemotherapeutic compositions). In addition, such images may also or alternatively serve as a basis for surgical techniques to remove tumors. Additionally, this in vivo imaging technique can also identify and localize tumors in patients with tumors (due to the presence of other biomarkers, metastasis, etc.), but tumors cannot be identified by traditional analytical techniques. All of these methods are features of the present invention.
本发明提供的体内成像和其它诊断技术在人患者(例如,以前未诊断具有癌症的患者,或在癌症恢复/康复期的患者)中检测微转移是非常有用的。例如,在所有癌细胞中占90%的癌细胞可用CD38抗体偶联组合物染色鉴定。用单克隆抗CD38抗体和其它此处所述的CD38BPs的检测可作为存在侵略性/入侵性癌的暗示,也或选择性地用针对这种微转移的相关单克隆抗CD38抗体、CD38BP或相关组合物治疗来提供可行性的暗示。另外,与癌细胞相关的单克隆抗CD38抗体利于区分这种癌相关组织和来自正常细胞的其它形式CD38相关的细胞。The in vivo imaging and other diagnostic techniques provided by the present invention are very useful in detecting micrometastases in human patients (eg, patients not previously diagnosed with cancer, or patients in recovery/convalescence from cancer). For example, cancer cells accounting for 90% of all cancer cells can be identified by staining with CD38 antibody conjugate composition. Detection with monoclonal anti-CD38 antibodies and other CD38BPs described here may be indicative of the presence of aggressive/invasive cancer, or alternatively with related monoclonal anti-CD38 antibodies, CD38BPs or related Composition treatments to provide a hint of feasibility. In addition, monoclonal anti-CD38 antibodies associated with cancer cells facilitate the distinction of such cancer-associated tissues from other forms of CD38-associated cells from normal cells.
在一个技术方案中,本发明提供体内成像方法,其中本发明的CD38BP,譬如抗CD38抗体与促进检测的无线电不透明试剂偶联,将偶联的抗体给药宿主,譬如通过注入血液中,然后检测宿主中标记抗体的存在和定位。通过这种技术和任何其它此处提供的诊断方法,本发明提供了在人患者或采自人患者的生物样品中筛选疾病相关的细胞存在的方法。对诊断成像而言,可将放射性同位素与CD38BP通过中间功能基团直接或间接结合。有用的中间功能基团包括螯合剂,例如乙二胺四乙酸和二乙烯三胺五乙酸(参见例如US5,057,313)。在这种放射性同位素偶联的CD38BPs参与的诊断检测中,递送到患者的偶联的肽的剂量典型地维持在尽可能低的水平,使同位素具有最小半衰期、在机体具有最小滞留时间,同位素数量最小,从而进行检测和精确测定。In one embodiment, the invention provides a method for in vivo imaging wherein a CD38BP of the invention, such as an anti-CD38 antibody, is conjugated to a radio-opaque reagent that facilitates detection, the conjugated antibody is administered to a host, such as by infusion into the blood, and detection is then performed. Presence and localization of labeled antibodies in the host. By this technique and any other diagnostic method provided herein, the present invention provides methods of screening for the presence of disease-associated cells in a human patient or a biological sample taken from a human patient. For diagnostic imaging, radioactive isotopes can be directly or indirectly combined with CD38BP through intermediate functional groups. Useful intermediate functional groups include chelating agents such as ethylenediaminetetraacetic acid and diethylenetriaminepentaacetic acid (see eg US 5,057,313). In diagnostic assays involving such radioisotope-conjugated CD38BPs, the dose of the conjugated peptide delivered to the patient is typically kept as low as possible to minimize the half-life of the isotope, the minimum residence time in the body, the amount of isotope Minimal for detection and precise measurement.
除了放射性同位素和无线电不透明试剂外,可使用与染料(譬如偶联生物素-链亲和素复合物)、造影剂、荧光化合物或分子及用于磁共振成像(MRI)的增强试剂(例如顺磁性离子)(参见例如美国专利6,331,175,它描述了MRI技术和与MRI增强试剂偶联的抗体的制备)偶联的CD38BPs进行诊断方法。这种诊断/检测试剂可选自用于磁共振成像的试剂和荧光化合物。为了加载诸如抗体,偶联放射性金属或顺磁性离子的成分这样的CD38BP,需要使其与具有连接多个可结合离子的螯合剂基团的长尾的试剂反应。这种尾可以是多聚体,譬如多聚赖氨酸、多糖 或其它衍生的或具有可与螯合剂基团,譬如例如卟啉、多胺、冠醚、二缩氨基硫脲、聚肟等已知用于该目的的悬挂基团的衍生链。可用标准化学法将螯合剂与CD38BPs偶联。螯合剂通常通过可与分子形成具有最小免疫反应性丢失和最小聚集和/或内部交联的基团与CD38BP连接。其它不常用的将螯合剂与抗体偶联的方法和试剂在例如US4,824,659中描述。潜在有用的金属螯合剂组合物的实施例包括2-苯甲基-DTPA及其一甲基和环己基类似物,使用一般能量范围为60到4,000keV的诊断性同位素,例如125I、123I、124I、62Cu、64Cu、18F、111In、67Ga、67Ga、99Tc、 94Tc、11C、13N、15O和76BR进行放射性成像。这些和类似的螯合剂在与非放射性金属,譬如镁、铁和钆结合时,可与CD38BPs联合用于MRI诊断方法。大环螯合剂,例如NOTA、DOTA和TETA可与各种金属和放射性金属一起使用,特别是分别与镓、钇和铜的放射性核一起使用。可通过剪辑目标金属的环体积而使这种金属-螯合剂复合物非常稳定。其它诸如大环聚醚这样的与核素,例如进行RAIT的223Ra稳定结合的环状螯合剂也适用于诊断方法中。In addition to radioisotopes and radio-opaque agents, dyes (such as conjugated biotin-streptavidin complexes), contrast agents, fluorescent compounds or molecules, and enhancing reagents for magnetic resonance imaging (MRI) (such as cis Magnetic ions) (see, eg, US Pat. No. 6,331,175, which describes MRI techniques and preparation of antibodies conjugated to MRI-enhancing reagents) conjugated CD38BPs for diagnostic methods. Such diagnostic/detection reagents may be selected from reagents and fluorescent compounds used in magnetic resonance imaging. To load a CD38BP such as an antibody, a component conjugated to a radioactive metal or a paramagnetic ion, it needs to be reacted with a reagent having a long tail linking multiple ion-binding chelator groups. Such tails can be polymeric, such as polylysine, polysaccharide or other derivatized or have chelating agent groups, such as for example porphyrin, polyamine, crown ether, thiosemicarbazone, polyoxime, etc. Derivatized chains of pendant groups are known for this purpose. Chelators can be coupled to CD38BPs using standard chemistry. Chelators are typically attached to CD38BP through groups that can form with the molecule with minimal loss of immunoreactivity and minimal aggregation and/or internal crosslinking. Other less common methods and reagents for coupling chelators to antibodies are described, for example, in US 4,824,659. Examples of potentially useful metal chelator compositions include 2-benzyl-DTPA and its monomethyl and cyclohexyl analogs, using diagnostic isotopes such as 125 I, 123 I , 124 I, 62 Cu, 64 Cu, 18 F, 111 In, 67 Ga, 67 Ga, 99 Tc, 94 Tc, 11 C, 13 N, 15 O and 76 BR for radiographic imaging. These and similar chelators, when bound to non-radioactive metals such as magnesium, iron and gadolinium, can be used in MRI diagnostic methods in conjunction with CD38BPs. Macrocyclic chelators such as NOTA, DOTA and TETA can be used with various metals and radiometals, especially with radionuclides of gallium, yttrium and copper, respectively. This metal-chelator complex can be made very stable by clipping the ring volume of the target metal. Other cyclic chelators such as macrocyclic polyethers that stably bind nuclides such as223Ra to perform RAIT are also suitable for use in diagnostic methods.
因此,本发明提供诊断型CD38BP偶联物,其中CD38BP与造影剂(例如用于磁共振成像、计算机X线断层摄影术或超声造影剂增强试剂)或放射性核素,例如γ-、β-、α-、俄歇电子或正电子发射同位素偶联。其它有用的偶联CD38BPs在其它地方描述,可用于本发明提供的诊断方法和组合物(例如诊断试剂盒)中。Accordingly, the present invention provides diagnostic CD38BP conjugates, wherein CD38BP is combined with a contrast agent (e.g. for magnetic resonance imaging, computed tomography or ultrasound contrast agent enhancing reagents) or a radionuclide, such as γ-, β-, α-, Auger electron or positron emitting isotope coupling. Other useful conjugated CD38BPs are described elsewhere and can be used in the diagnostic methods and compositions (eg, diagnostic kits) provided herein.
在一个技术方案中,本发明提供诊断癌症的试剂盒,包括含诸如抗CD38抗体这样的CD38BP和一种或多种检测CD38BP与CD38肽结合的试剂的试剂盒。例如,试剂可包括荧光标签、酶标签或其它可检测标签。试剂也可包括二抗和三抗及用于酶反应的试剂,其中酶反应可产生可显现的产物。在一个技术方案中,本发明提供诊断试剂盒,在合适的容器中含一种或多种标记或未标记形式的本发明诸如抗CD38抗体这样的CD38BPs,间接检测法中的温育试剂,及根据标记的状态,在这种检测中进行检测的底物或衍生的试剂。也包括对照试剂和用途说明书。In one technical solution, the present invention provides a kit for diagnosing cancer, including a kit comprising CD38BP such as an anti-CD38 antibody and one or more reagents for detecting the combination of CD38BP and CD38 peptide. For example, reagents may include fluorescent tags, enzyme tags, or other detectable tags. Reagents may also include secondary and tertiary antibodies and reagents for enzymatic reactions that result in visualized products. In one embodiment, the invention provides a diagnostic kit comprising, in a suitable container, one or more CD38BPs of the invention, such as an anti-CD38 antibody, in labeled or unlabeled form, an incubation reagent in an indirect assay, and Depending on the state of labelling, the substrates or derivatized reagents are detected in this assay. Control reagents and instructions for use are also included.
也提供了诊断型试剂盒,通过诸如偶联/标记的抗CD38抗体这样的CD38BP在组织样品或宿主中检测细胞活性或检测CD38肽的存在。在这种诊断型试剂盒及其它地方所述的用于治疗用途的试剂盒中,典型地可在试剂盒中以冻干形式,单独或与其它针对靶细胞或肽的抗体一起提 供CD38BP。典型地,也包括药学上可接受载体(例如惰性稀释剂)和/或其成分,例如Tris、磷酸或碳酸缓冲液、稳定剂、防腐剂、生物杀灭剂、生物杀灭剂、惰性蛋白,例如血清白蛋白等(典型地,装在单独容器中,用于混合)及其它试剂(典型地也在单独的容器中)。在特定试剂盒中,也包括可结合抗CD38抗体或其它CD38BP的第二抗体,它典型地存在单独的容器中。第二抗体典型地以与本发明的抗CD38抗体或其它CD38BP相似的方式与标记物偶联和配制。用上述方法CD38BPs可用于区分癌/肿瘤细胞的亚组,并鉴定这种细胞及相关的组织/生长。Also provided are diagnostic kits for detecting cellular viability or detecting the presence of CD38 peptides in tissue samples or hosts via CD38BP such as conjugated/labeled anti-CD38 antibodies. In such diagnostic kits, as well as kits for therapeutic use as described elsewhere, CD38BP will typically be provided in the kit in lyophilized form, alone or with other antibodies directed against the target cell or peptide. Typically, pharmaceutically acceptable carriers (such as inert diluents) and/or components thereof, such as Tris, phosphate or carbonate buffers, stabilizers, preservatives, biocides, biocides, inert proteins, are also included, Examples include serum albumin etc. (typically in separate containers for mixing) and other reagents (also typically in separate containers). In certain kits, a secondary antibody that binds the anti-CD38 antibody or other CD38BP is also included, typically in a separate container. Secondary antibodies are typically conjugated and formulated to the marker in a similar manner to the anti-CD38 antibodies or other CD38BPs of the invention. Using the methods described above CD38BPs can be used to differentiate subgroups of cancer/tumor cells and to identify such cells and associated tissues/growths.
在一个实施例中,CD38BP或抗CD38抗体可加到硝酸纤维素或其它可固定细胞、细胞颗粒或可溶性蛋白的固相支持物上。然后在用可检测标记的CD38肽或抗体处理后用合适的缓冲液洗涤支持物。然后用缓冲液洗涤固相支持物以除去未结合的肽或抗体。然后可通过已知的方法步骤检测固相支持物上结合的标记物的量。In one embodiment, CD38BP or an anti-CD38 antibody can be added to nitrocellulose or other solid supports that can immobilize cells, cell particles or soluble proteins. The support is then washed with a suitable buffer after treatment with the detectably labeled CD38 peptide or antibody. The solid support is then washed with buffer to remove unbound peptide or antibody. The amount of bound label on the solid support can then be detected by known method steps.
连接的与暴露的底物反应的酶可用于产生可被检测的化学基团,例如,通过分光光度测定、荧光测定或视觉观察的方法检测CD3 8BP偶联物和/或融合蛋白。可用作可检测标记CD38BPs和抗CD38抗体的酶包括苹果酸脱氢酶、葡萄球菌核酸酶、δ-5-类固醇异构酶、酵母乙醇脱氢酶、α-甘油磷酸脱氢酶、丙糖磷酸异构酶、辣根过氧化物酶、碱性磷酸酶、天冬酰胺酶、葡萄糖氧化酶、β-半乳糖苷酶、核糖核酸酶、尿素酶、过氧化氢酶、葡萄糖-6-磷酸脱氢酶、葡糖淀粉酶和乙酰胆碱酯酶。也可以用荧光化合物标记CD38BP。当荧光标记的抗体暴露在合适波长的光下时,可通过荧光检测其存在。最常用的荧光标记化合物是荧光素异硫氰酸盐、若丹明、藻红蛋白、藻蓝蛋白、异藻蓝蛋白、o-邻苯二甲醛和荧光胺。Linked enzymes that react with exposed substrates can be used to generate chemical moieties that can be detected, for example, by spectrophotometric, fluorometric, or visual inspection of CD3 8BP conjugates and/or fusion proteins. Enzymes that can be used as detectable markers for CD38BPs and anti-CD38 antibodies include malate dehydrogenase, staphylococcal nuclease, delta-5-steroid isomerase, yeast alcohol dehydrogenase, alpha-glycerophosphate dehydrogenase, triose Phosphate isomerase, horseradish peroxidase, alkaline phosphatase, asparaginase, glucose oxidase, beta-galactosidase, ribonuclease, urease, catalase, glucose-6-phosphate Dehydrogenase, glucoamylase, and acetylcholinesterase. CD38BP can also be labeled with a fluorescent compound. The presence of fluorescently labeled antibodies can be detected by fluorescence when exposed to light of the appropriate wavelength. The most commonly used fluorescently labeled compounds are fluorescein isothiocyanate, rhodamine, phycoerythrin, phycocyanin, isophycocyanin, o-phthalaldehyde, and fluorescamine.
诸如抗CD38抗体的CD38BPs也可用荧光发射的金属,譬如152Eu或其它镧系列金属进行可检测标记。例如,这些金属可被抗CD38抗体通过金属螯合基团例如二乙三胺五乙酸(DTPA)或乙二胺四乙酸(EDTA)进行连接。CD38BPs such as anti-CD38 antibodies can also be detectably labeled with fluorescent emitting metals such as152Eu or other lanthanum series metals. For example, these metals can be attached by anti-CD38 antibodies via metal chelating groups such as diethylenetriaminepentaacetic acid (DTPA) or ethylenediaminetetraacetic acid (EDTA).
CD38BPs和抗CD38抗体也可通过与化学发光化合物偶联而进行可检测标记。然后通过检测在化学反应中升高的荧光的存在来测定化学发光标记的CD38-BP的存在。特别有用的化学发光标记化合物的实施例有发光氨、异氨基苯二酰肼、theromatic吖啶酯、咪唑、吖啶盐和草酸酯。CD38BPs and anti-CD38 antibodies can also be detectably labeled by conjugation with chemiluminescent compounds. The presence of chemiluminescence-labeled CD38-BP is then determined by detecting the presence of fluorescence that increases during the chemical reaction. Examples of particularly useful chemiluminescent labeling compounds are luminol, isoaminophthalhydrazide, theromatic acridinium esters, imidazoles, acridinium salts and oxalates.
同样,生物发光化合物可用于标记CD38BP。生物发光是一种在生物系统中发现的化学发光,其中催化蛋白可增加化学发光反应的效率。生物发光蛋白的存在通过检测荧光而测定。用于标记的重要的生物发光化合物有荧光素、荧光素酶和发光蛋白质。例如如果可检测标记是放射性γ发射者,则标记肽或抗体、抗体片段或衍生物的检测可通过闪烁计数来完成,如果标记是荧光材料,则通过荧光计数来检测。对酶标记而言,可通过使用酶底物的比色方法进行检测。也可通过将底物的酶反应程度与类似制备的标准品进行视觉比较而进行检测。Likewise, bioluminescent compounds can be used to label CD38BP. Bioluminescence is a type of chemiluminescence found in biological systems where catalytic proteins increase the efficiency of the chemiluminescent reaction. The presence of bioluminescent proteins is determined by detecting fluorescence. Important bioluminescent compounds for labeling are luciferin, luciferase and luminescent proteins. For example, detection of the labeled peptide or antibody, antibody fragment or derivative can be accomplished by scintillation counting if the detectable label is a radioactive gamma emitter, or by fluorescence counting if the label is a fluorescent material. For enzyme labels, detection can be performed by colorimetric methods using enzyme substrates. It can also be detected by visual comparison of the extent of enzymatic reaction of the substrate with similarly prepared standards.
这些和其它诊断技术可用于筛选任何合适的针对CD38肽或CD38片段的材料。这些被筛选的材料的实施例包括例如血液、血清、淋巴、尿液、炎症流出液、脑脊液、羊水、组织提取物或组织匀浆等。但本发明不限定仅检测这些样品,本领域技术人员可确定使用其它样品的合适条件。These and other diagnostic techniques can be used to screen any suitable material against CD38 peptides or CD38 fragments. Examples of these materials to be screened include, for example, blood, serum, lymph, urine, inflammatory effluent, cerebrospinal fluid, amniotic fluid, tissue extracts or tissue homogenates, and the like. However, the present invention is not limited to testing only these samples, and those skilled in the art can determine the appropriate conditions for using other samples.
可通过从患者中除去组织样品,并对这种样品提供本发明的标记CD38BPs,譬如抗CD38抗体而进行原位检测。通过对生物样品使用或覆盖标记的CD38BP,譬如标记的抗CD38抗体(或片段),可提供本发明的CD38BP、抗CD38抗体(或片段)。通过使用这种流程,不仅可测定CD38或CD38片段的存在,也可以测定这种肽在被检测的组织中的分布(例如,以评估癌细胞的散布)。通过本发明,技术人员应知道,可改变任何各种组织学方法(例如染色流程)以进行原位检测。In situ detection can be performed by removing a tissue sample from a patient and providing this sample with labeled CD38BPs of the invention, such as an anti-CD38 antibody. The CD38BP, anti-CD38 antibody (or fragment) of the present invention can be provided by using or covering a labeled CD38BP, such as a labeled anti-CD38 antibody (or fragment), on a biological sample. By using this protocol, not only the presence of CD38 or CD38 fragments can be determined, but also the distribution of this peptide in the tissue being examined (eg, to assess the dissemination of cancer cells). With the present invention, the skilled artisan will appreciate that any of the various histological methods (eg, staining protocols) can be modified for in situ detection.
